My first thought would be a Shure SM7b, though it's over your price range. Used, it would probably squeek in, though I don't see too many used ones - people tend to keep them.
Same applies for the EV RE-20.
Same for the Beyer M88.
So, eliminating those, I think I would actually be willing to consider taking the plunge on a mic that I've got no personal experience with. Do some research on the
Heil PR30 and see if you're struck the same way I am.
Tape Op Magazine did an interview with Mr. Heil a couple of issues ago, and that plus the things I've read on Gearslutz and the Tape Op boards makes me very curious.
These are all dynamic mics. Unless I've got a lot more to spend on a vocal mic, (Neumann KMS 105, Beyer M500 - and up) I'd probably stay dynamic - and even then there's a good chance I'd stick with the dynamics anyway.
