I actually bought
2 crap kits before venturing out and finding the better stuff.

My first bit was an eGo pass
through, a couple of SmokTech eGo dual-coil cartomizers, and a couple of small bottles of
juice. That cost about half what I let go of for just one of the crap kits.
If you like the form factor of an analog, I personally like the Volt from Smokeless Image. (This is what I use at work.) Good equipment (so far), good flavours, and the cartos are easily refillable. The price is also a screamin' deal. This is what I
wish i'd bought first.
I'm in agreement with most everyone else, though. eGo/510 is a really good and easy way to go, especially for us n00bs.
