Recently asked a similar question in "Other Instruments": Electronic Drums - Any BC Knowledge Out There? - Other Instruments - Basschat
My son wanted a drum kit, an electronic kit was the obvious choice, so I managed to track down a second hand Alesis Nitro Mesh kit. My son's made up with it, it sounds really good, and there's a load of tutorial stuff available online if you register the kit with Alesis (though he's happiest to bang about playing along with Spotify). The Bass drum pad is the usual rubber, but the snare & toms are mesh heads.
The more money you have available, you'll obviously get a better kit, but the mesh heads are the way to go.
Good luck.
