My word, you do start early in the day! My gratitude for the time taken to reply to my lengthy post. So sorry about the name mixup - either my ears are lousy or my memory; probably the latter. I do recall vividly your helpfulness and enthusiasm which was terrific.
You have confirmed my impression that you've spent a lot of effort (and no doubt money) to develop as good a product as possible which is reassuring and all to the good. I'm mildly disappointed that the black EVO will have a smaller battery but quite understand your reasoning about stock-holding etc. I agree that your prices are very competitive in this marketplace and I'd not want that to change. Will still look out for the new black ones and likely purchase when they become available. Hopefully we'll hear about it here first!
I'm reassured that your cartridges can be refilled and thanks to both yourself and BadSeed for the info and picture. As for the "Faffing about/another income stream", went back and looked again and it's a lousy sentence isn't it?

Could do better - so let's try again. I was asking about you selling empty cartridges and they were the proposed additional income stream. The "faffing about" was my notion of washing out the 'wool' to reuse prefilled carts in the absence of empties being available to buy as such. If you do start selling them and I get a black EVO, I'm sure I would be in the market for these too.
You've raised the point of spend versus conventional cigarettes so I'll now bore you stupid with my calculations!

I did do quite a bit of research before my first purchase including costings so here are the figures and assumptions I was working from:
Existing costs based on 30/day, mixture of Marlboro 100's + tobacco used in Belgam machine with premade tubes - approx £25 a week. That is based on a recent spend of £300 in Belgium which was intended to last about 90 days or 12-13 weeks. Total of 2700 cigs - god, doesn't that sound awful! Obviously that is less than UK standard full price would be but we're fortunate in living near enough to the ferries/Chunnel that 4 or 5 trips over a year are quite viable. We have a nice day out and buy other stuff in France as well. I'll miss that if be don't do it anymore!
Option 1) Estimated costs for e-cigs for same 90 day period, based on buying DSE901b starter kit, 6 spare atomisers, (worst case scenario that I kill one every 2 weeks) plus couple of spare batteries (possibly pessimistic guess) plus 450 prefilled cartridges (to yield 2700 cigs-worth based on 6 cigs per cart) sadly came out at £358. Admitted, that was based on largest part of the cost being cartridges - at £15 for 25 from one of your competitors, which certainly isn't the best price available.
Option 2) Recosted on identical hardware items, no prefilled carts, plus 50 empty refillable cartridges plus 180ml liquid (based on usage of 2ml/day, which seems generous) came to a rather more user-friendly total of £213.50.
That was where I got the notion that using prefilled cartridges could rack up pretty fast. I do accept that purchase of your EVO cartridges at today's price on your site would come in at a lot less than Option 1(although not less than Option 2) - but can I purchase at trade prices as a normal punter?
In addition, now I am no longer an e-cig 'virgin' and have actually been using some liquids and used the trial carts that came with the starter pack I have learnt a bit more. The generic 901 carts do, as others have said here, taste appalling. I would have to try yours before I could comment. I doubt I'm using as much as 2ml/day, and anyway am getting some of the high-strength 36mg liquid which I intend to dilute with glycerine (£1.25/100ml at my local pharmacy) so expect my cost to come down below the £200-mark for that mythical 90 days, even with spending out for extra flavourings if I decide to do that. I'm also hoping to take good care of my atomisers and batteries to let them last as long as poss.
As regards liquids, yes I did do my research first; including reading the famous lab report in full. I stand by my original observation that publishing a test report is a great selling point. I can also understand why Jason (Pillbox38/Totally Wicked) feels the costs for this justify his charging a premium price for his products and his customers are voting with their hard-earned. Even if some of them do grizzle!
I believe Kate agrees with me, and having read your reply to her am disappointed that you don't seem willing to post any test reports - you could edit exact quantities to protect 'commercially sensitive' info. A simple list would have answered her question of "What is in your cartridges?". All we seem to have learned that your liquid is sourced from China and not the US or Europe.
Oh, ****, this has turned into an epic again - sorry! Still hoping to be a customer, and congrats on having started a lively thread.
PS Love your Ronseal 'signature'
