Sennheiser offers a 3-mic kit for drums, I believe they're E604s, which I have READ sound 'better' than SM57s. I don't know--they're about $20 USD more than SM57s when purchased in the 3-pak.
Also, I found a May Sennheiser 604 SD/tom mic that mounts inside the drum, which I think would be very nice if it captures conga nuances. It would be great to hear from anyone who has actually done this with conga vs tom. You can see 'em at

I have NO experience with recording at all...but I do find that SM57s seem to be the most consistently recommended mic for drums (incl conga) in the "low-end" price range. Just repeating what I've heard...sorry.
