Fastech has about the best price on the Vamo V5, it's about $29 for just the device. I have a stainless and a black chrome one both from there and they work great. I wouldn't recommend the starter kit from there at all, it comes with two cheapo 18350 batteries, charger and (2) CE4 Clearomizers that taste like burnt plastic.
Depending on your budget and your patience, you could get the Vamo from FT and shop around for the charger and batts. I would also recommend the Nitecore i2 charger and Panasonic, eFest or AW batteries, I have all 3 brands and they all work good, it's well worth it to buy good batteries, both for your safety and they just perform a lot better. If you buy 2 of the 18350's you can either stack them both in the Vamo, or just use 1 if you remove one of the extension tubes. It cuts the length of the device in half which is nice sometimes. If you just have the one 18650, you are limited just the one size, it's pretty big once you get a tank on it.
The iClear 30 does work well on there as well as a Protank 2 or 3, both are similar in size and function and capacity. The PT's are a little more durable with the Pyrex glass tank opposed to the plastic iClear. Some juice will crack the plastic tanks and leak everywhere, also like Dadrun said, don't forget the replacement coils for whichever tank you go with. The PT 3 coils are around $10 for a five pack, they are a little more as they are dual coil, the PT 2 is a single coil.
I just thought I'd throw my two cents in as I am a big fan of the Vamo, I have a total of about 10 different mods and I still use my Vamo/PT 3 just about every day
Good luck
