yay! someone only i can relate to!
anyway, yes you can. the top two electronic kits on the market are Rolands and Yamaha. i suggest Yamaha because thats what i use and its more adaptable to foreign triggers. You can buy a module seperately and then use wires and triggers to run through to the module and listen from headphones. if your plannning on recording your set, then you need a USB cable from your module to the computer. from there you need a MIDI recording program. from the module you can do this: set volume, sensetivity, sound, pitch, output, and other cool things. Hell, you can make your snare drum your cymbal (i dont recomend this though due to screwing you up!) Electric sets in general are EXPENSIVE. they all go by a basic principle too: pad size. The bigger your pad size then the more expensive it will be. Look at it this way, its a lot easier to hit a big pad then a little one! Roland makes some NICE sets and they have a cool MESH head. The head gets more rebound and makes it very similar to a real head. (in other words its not a rubber pad!) To rap it all up, you need to research and have a spending limit. Full electric sets run from 700$ to 4500$. Big difference but it all depends on what you use it for.
Hope that helps!
