drum mics
hey, i'll tell you straight up that some of the cheapy mics sound just fine. i had mics from K-Mart (4.99 each) which sounded great for what they were. I think it depends on your sound and what you are looking for. remember, a lot of the judgement on mics are from their frequency response. so what if you got a K-Mart mic that only picks up 100hz-12khz? your drums probably won't even attempt to fill that bandwidth... as for pure sturdyness, the plastic mics suck, but they are going to be recording the drums, not supporting weight or keeping grandma's life support working. i upgraded my snare mic to a sm57 and together with the kmart cheapies it sounded great. plus for the price of one sm57 you could get 15 kmart specials. other than that, CAD makes some good cheap(but professional) drum mics(4 for 200$) that sound really good. just shop around, try out every mic you can get your hands on and only then after you get all your research done, buy what you want, not what others say are good or not. RS mics are probably fine if you like the sound.
aside from my rant,
1 sm57 goes on the snare facing in from the hi hat side(if the drummer does not hit it) to reject the hat sounds, the other in the bass drum about 4 inches from the back head and tilt it about 30-45 degrees off center(so the actual shockwave does not hit the mic element directly.. that would be bad) and put the radio shack cheapies on either side of the kit but just in front of the kit kinda pointing at the hihats and the ping if you have one. adjust your eq and pan to taste. if you get phase issues, try moving the mics closer or farther away from each other. i don't think the cheapies would have the upper frequncy response you need to place them overhead( the cymbals will wash them out with midrange and possibly clip the signal if they are too close.) so experiment with the mics to the sides of the kit and you will probably get close to what you are looking for and still using the RS mics.
