Do a search on the Studio Projects C1, B1, Shure SM-57, and the Marshall V67G... they're all in your price range and have received lots of positive feedback. Also, some people have had good results with the Oktava 319. Audio Technica also makes very good LDCs for the money, as does RODE.
If I were buying my first LDC, I'd check out the Studio Projects B1... they cost around $80, and are fairly neutral sounding. I own two of them (along with many other more expensive mics), and feel they were well worth the money.
