I haven't contributed to the forum in quite some time, but here's my 2 cents. I would start with a good all 'round mic that can be used in many different situations - like a shure sm57. This is a very useful mic (requires no phantom power or special stands/mounts) that you will always want to have on hand and can be used on a variety of instruments.
Often times more expensive mics require more expensive preamps and more expensive treated rooms to realize their true potential. This always leads developing more expensive GAS.
Even with a great mic, positioning is crucial. Proper positioning of microphones can have a greater impact on your captured sound than the actual microphone used.
Get a mic, any mic. Do some internet searches on mic positioning of your source. Start experimenting, figure out what works or doesn't and most of all, have fun.
