For under $60, the classic recommendation would be a Shure SM57 or
one of the other "Unidyne III" microphones similar to it like the Shure
545. This would be the pricing for a used one BTW.
The most affordable mic pre that would offer "pro" sound would be the
Studio Projects VTB-1 IMO, which is expected to have a price decrease to
around $130, in 6 weeks or so. Website is

One other reasonable way to go would be to get one of the UB series
Behringer mixers, and get something like a Studio Projects B1 (est. $80).
A condenser microphones like the B1 will do better with a cheap mixer's
pre's than a dynamic microphone like the Shure SM57.
At
www.pmiaudio.com they may still have some demo Joe Meek MQ1
units on sale ($130?), that include a mic pre, compressor, and EQ.
You'd need to see if your PC is compatible to be safe.
