Which to buy - 650 or 1300?
I would highly recommend a 1300 battery. I almost went with a 650 myself, but they were sold out when I was ordering. I'm very happy that I went with the bigger one in the end. It's definitely not as big as I thought it would be and a charge will last me almost two days at my vape pace.
Low resistance cartomizers? relevant to this product?
The Echo is an 808 device, so you can use any 808 cartomizer which you like. You can certainly use a low res one since you'll have either a 650 or 1300 mAH battery @ 4.2-3.7 volts. The
mega cartos that come with the Echo starter kit are not low res, although there is a
dual coil version that most people seem to prefer.
Need a link to the perfect starter kit?
There's an
Echo kit on sale over at Smoketek. It looks to be the best deal at the moment. It's $38.95 and comes with two batteries, a wall and usb charger and two Echo cartomizers. I would also make sure to get some extra cartos if it's within your budget. A box of dual coil Echomizers to try and a box of any type of normal 808 cartomizer to test juices on. You don't want to fill up a 3mL carto and then decide you don't like the juice!
I need to put something in the darn thing, right? Are there sample kits that are pre filled cartomizers or do I need to learn this DIY filling method right now if I want to use the echo?
Echo cartomizers DO NOT come prefilled which is probably a little annoying for beginners. You can always pick up other 808 cartos that are prefilled, but filling your own is pretty easy once you get the hang of it. Echo cartomizers are huge, so the best way to fill them is with a syringe. All you do is fill up your syringe, stick it down between the stuffing and the metal edge of the carto until you hit the bottom and squeeze making sure to evenly fill from each side.
Need recommendations for something approximating camel menthol for a pack a day smoker. Though I also am willing to try other things.. Maybe as part of a sample kit.
I'm a huge fan of
Backwoods Brew as I think they have the best tobacco flavors. Casablanca is their Turkish type tobacco flavor. They don't have a sample pack though, which is a good idea if you're just starting out. You could try
The Vapor Room. They have some nice sales for first time buyers and offer a sampler. I would suggest getting a few juices that are out of your comfort zone at first. I thought I would hate anything other than tobacco and got a free sample of Waffle because I thought it sounded hilarious. It turned out to be one of my favorite flavors!
How much eliquid to buy at first?
You can never go wrong with too much juice.

Just try not to buy huge bottles of one flavor until you've tried it. I made this mistake at first and was stuck with huge bottles of stuff I hated. Order samples or 15mL of one flavor and if you like it, then go back and get a huge bottle!
I saw mention of battery issues in the echo thread, nine hour charge time. Then there was talk of an upgraded echo and I don't know if the problem went away.
I would say nine hours is probably about right. That is the only thing that annoyed me about Echo at first, but now I charge one while I sleep and it's fresh by morning. Since the 1300 battery will last me two days and I have two of them, I never really worry about the charge time myself. YMMV though and perhaps someone else can chime in on this issue!
If there's anything confusing in my answers, I can totally clarify. When I was looking to buy my first device, I was absolutely dumbfounded by all the jargon that goes with e-cigs. Just take your time and buy whatever you think will keep you off those nasty ciggies!
