4 mics? you could get an awesome drum recording with 4... (assuming the kit sounds good).

I've used this technique, but a variation with only 3 is to measure the distance between the two overheads (let's call this'B'), then put a microphone in front of the kick that distance ('B') from the centre of the snare - it'll emphasise the kick, and give more depth to the toms too.
Something like this:

I've had very good recordings from a pair of SE2000s (£80 condensers) as overheads, and an SE 2200 (also a Beyer Dynamic M834, but that's way over budget...) in from of the kick.
