another vote for the 57. can't go wrong. most recorded tracks use that. but depends on what kinda sound you after. even mics have their own characteristics. there's tons of info on the net about mic combi's for recording, and crucially, the placement and room verb you want as well. the thing is, to start off, the SM57 will suit you best.
tremonti blew several ribbon mics while recording his latest album with alter bridge apparently. the chugg from the mesa stacks apparently rattled it too much. zakk wylde's engineer uses a combi of condensers and the good ol' 57 to record his marshall stacks. and if its a 4x12, he actually placed the mic at the top right corner of the stack, rather than aiming it at the cone itself off-axe. its really cool. but this was for the black label society album. could be a different sound they were after? dunno.
anyways, best is, get the 57, and play around with it. got more cash, then start building your mic cabinet...heh.
