I really am a drummer and have been playing for more years than I care to think about, but if you want a cheap 'IN' to learning for figuring out, go and get a basic practice kit. They usually focus on making the playing feel right and have nothing like the correct sound, so if you wanted to jump from practice to real it should feel the same.
Most of the inexpensive (and some expensive) electronic kits I have played put all the emphasis on gee wiz sounds but feel crappy to play.
It depends what you want.
If its gee wiz sounds and messing about, go for the cheapest that makes the sounds you like.
But if you want to learn to play, get a no sound practice kit.
Please remember that this came from a guy who will never ever replace his lovely black Premier XPK for the world
Good luck.
