I agree IGO's are good entry level RDA's for the price point. However a lot of RDA's are being introduced that do compete with the price. While they may be a couple dollars more it is worth it for the additional features. I payed about the same for my Tobh as I would have for a new IGO. And IMO the Tobh is just as easy to build on as a IGO W4.
About the Magma's, honestly I would not hesitate to buy one and will order one as soon as funds allow for it. I think the issues with the first run can be chalked up to a QC issue more than likely. According to everything I have read the V2 is top notch and all the issues have been fixed.
As far as carrying entry level or more advanced gear. Well either or both would fit your plan I believe. Offering the advanced gear will cater to those people that are more progressed in their vaping journey. It will also appeal the hobbyist vapers. Both of which are included in the niche market you aim to target. You are also passionate about introducing dripping to the people that have never tried it before. Thus, entry level products would also fit nicely into your overall goal for your business. Just my
I can't comment on specific RBAs or RDAs, so I'll leave that to others, but here's an idea:
I know you want to urge people toward dripping and RDAs, but I think with regard to your selection of tanks, you could do better than the evods. I use my evod glasses from time to time because they're small (great for errand running), but I think if you carry just a few tanks, you would be better served by offering Aeros and Nautiluses.
Then include a little bit of text about why you think RBAs and RDAs are an improvement over tanks, followed by recommended starter equipment (kayfun, igo, etc.). From there, you can lead to more advanced equipment.
You don't really need to carry a large selection in any of the categories (maybe two or three items for each) just so long as they are highly recommended and well described. As added encouragement, a full description of exactly how to use them might persuade more people to buy. You can also include links to youtube reviews and how-to's. I think this kind of attention would help in several ways:
1. At the entry level (tanks) you will be providing people a way to enjoy your juices in the best way possible if they don't drip or rebuild. Many people who pick up your juice and, say, an evod will probably say, "meh." Whereas with an aerotank or nautilus, they will definitely appreciate the flavor a lot more.
2. A guided entry into the world of RBAs and RDAs will help those who are bewildered by the array of options out there. New vapers come onto ECF all the time who are interested in something better, but they just don't know what to get or, when they receive it, how to effectively use it. Yes, motivated folks will research and figure it out, but if you take some of the guess work out of the process, you might encourage more people to try it. And having help, right there on the site, on how to use it will keep customers happy. Hand-holding to be sure, but that might be what some people need.
3. With the advanced setups, you could potentially foster some community through comments/reviews. Those comments could then, in turn, help encourage entry-level users to step up.
Like I said, just some thoughts....
