How about a kick good mic, 57 on the snare and spend the additional money on a pair of nice large condensers for the over all kit sound. At 4050's are not to expensive and they sound real good on drums. Use mic placement, compression and a slight amount of eq to get the toms to come through. Another alternative is to just use one condenser to pick up the over all drum sound, it is mono but a lot of times it sounds very punchy and more to gether than a bunch of mics on the drums
