PV's are like juices...it's all subjective. I love all the mods I own and sold the ones I didn't. I started with a Joye 510..did I regret it?...no but it wasn't long before I discovered an eGo and bought it. The eGo was cheaper for a kit than the Joye 510 but it still got me off the smokes.
Whatever you buy, if it works to keep you from smoking, than it is money well spent. I don't care if someone paid $200 for a kit, if you quit smoking with it, it was money well spent...a person's health doesn't have a price tag. All ecigs (or almost all) can always be found cheaper if you do your homework.
