OK, I recommend getting an electronic drum set IF:
1. You are extrememly knowledgable on drums: materials, brands, tunings, thicknesses, brightness, decays, and about a billion other things.
2. You have excellent technique and years of drumming experience.
3. You plan on doing home recording, whether just for fun or professionally, for the rest of your life.
A cheap electronic kit is just not a good choice for recording (or anything for that matter

). Roland, imho, is better if you want to have a very versatile kit for playing live (or in church or some similar setting). Yamaha, though, is the best brand for recording. The dtxtreme IIs is only $2000, and the sky is the limit on the thing, literally. You can even import and/or create your own samples of SOUNDS, not only kits. However, the dtstreme IIs is now discontinued (GASP!!), as I have the official insider word that Yamaha is introducing a new kit at winter Namm. Undoubtedly, this new kit will be much more expensive, and I really can't think of how I would upgrade the dtxtreme IIs aside from adding more samples (you can add your own a custom samples already). I know musiciansbuy.com is offering very nice deals on their remaining dtxtreme IIs's, so go buy one before it's too late.
