depending on the equipment that you get for the money you can, you don't have to worry because for any of the stuff that I have seen that seems to be a pretty good deal.
Just to be safe look for a clearomizer that is made of pyrex if you want to vape a bunch of different flavors. I shop desertvapes and got
1x Innokin iClear X.I
1x Ego k etched maze battery
1x glass drip tip
1x eGo charger
for around 48 bucks with shipping. It works amazingly even after a few months.
