This guy has reviewed about 100+ e-cigs so far

This woman also does a nice comparison of three e-cigs the Zenith, Titan and Super
http://www.youtube.com/watch?v=sxOrMpt7rzE her channel also has some good insights into the world of e-cigs.
You cant go wrong with a Zenith or a Titan 510, Ive also bought products off both these websites before and had no problems. (Next day delivery on both)

Ive got a voucher code for liberro "imnew10" which gives you 10% any order as a first time customer, igetcha69 has a code for liberro as well "ECR69" which is apparently 15% off.
This code is for totallywicked "T4BE699" it gets you 7.5% off.
Oh one more thing, dont buy from a brand called blu, I've heard really mixed reviews about their e-cigs
Bit embarrassing but im really trying to throw myself into smoking e-cigs so Ive done my own review of the Zenith
http://www.youtube.com/watch?v=iKxHAPg4Q0A (its a bit long winded... heh) im going to do another review of the Titan on Tuesday, my friend already has one hence the recommendation.
