Honestly, I'm not sure I'd even go for a condenser if that's your budget. Condensers are a bit more sensitive than dynamics, sure, but that's a double-edged sword. Condensers also aren't as good at picking up high-SPL sound sources, which would be useful if you even wanted to close-mic an amplifier or drum. I figure if you're only going to have a few mics you might as well have one that would work pretty well on just about anything.
A few years ago, I'd have told you to just pick up an SM57 from somewhere. They are an industry standard and can be used on acoustics, snares, amps, voice, or whatever, really. But, after having the plastic grill snap off of several over the span of time, I would instead tell you to get an Audix i5. Very similar sound/usage profile to a 57, but the kicker is that the thing is literally clad in armor and can take any abuse you throw at it. Just my 2 cents, good luck!
