get 2 condensers and 2 dynamics use the recorder-man method on the overheads, and then mic up the snare and bass drum u might wanna dampen a lil, and tune or course. but my band did this and got a really good sound in an untreated room with decent acoustics and a tama swingstar.
I've only put off getting drum mics because when I recorded with a 4-track, I just stuck 1 mic in front of the drums and 1 at the snare and I kinda liked the sound...but that doesn't work with the new digital studio.
