IMHO the juice matters more than the ecig. at freedomsmokeusa.com they have a juice that tastes exactly like a burning cigarette, it's called PureCig. the higher the VG percentage, the more vapor you will get, and the 36 mg juice gives a great Nic buzz. as for the brand/style, that is totally personal preference. i have tried most of the major styles and found that the 510 gives the best throat hit and most flavor but with crappy battery life. the 801 gives slightly less flavor but more vapor and over double the battery life. the 901 is sort of in the middle of these 2, not particularly great at anything. the kr808d is the best compromise between the most vapor the best battery life and good battery life. so it really depends on what u r looking for most in an ecig. i get all my hardware from ecigsupply.com and bestecig.com, the latter of which is a chinese supplier. good luck
