The interface mentioned earlier should be fine. Any interface with at least 8 XLR inputs is gonna be good. If that tascam thing can do 10 or 12, go with it.
Offcenter was a guy in here that asked some drum questions and didn't like the answers so he went all pissy apeshit bananas on everybody. You showed hints of going that route, but you held back and that's cool. No need to apologize to me.
I'm telling you, your first tries at recording drums are probably gonna suck. That's just the way it is. I think it goes that way for everyone. That's why I suggested doing a lot of practice recordings first on stuff that isn't important. Nothing sucks worse than putting out a mediocre product and then a few weeks later learning a new trick or technique that gives you a huge improvement in sound. Then you're like, FUCK! I can tell you from personal experience that it's worth it to hone your skills before you go trying to record stuff that's really important to you. If you just wanna get it down on tape so you don't forget, well that's different. But if it's something you wanna be proud of for a long time, save it until you're ready. Anyway, recording drums is tough but it's very rewarding when you start getting it good. Not many people can really play the drums, and even fewer can record them well. It just takes practice.
