E-pipes may be simple, mechanical devices, they may contain some safety features and/or be variable wattage (VW). Users of mechanical or semi-mechanical devices should have knowledge of Ohm’s Law, battery safety, and be able to check the resistance of their atomizers (via ohm readers or multi-meter). If any of that seems unappealing, you can opt for kits geared more towards beginners (that can be just as high of quality in terms of the actual manufacturing of the pipe itself) or e-pipes that have regulated power.
Such a variety of electronic pipes are available, shopping for one can be quite entertaining! Models range from inexpensive, high production Chinese models, to mid priced items to unique, one of a kind, hand carved e-pipes. Prices range from about $30 to more than $400.
In the end, what you buy is only really limited by your wallet. There are artisan e-pipe makers as well as mass-produced e-pipes, so if the idea of an e-pipe piques your interest, do not be swayed one way or another by what you initially see: to is just the tip of the iceberg. Keep researching until you find one that appeals to you, either in its form factor or in its power capabilities.
