Try this...
I have a buddy who bought a (gasp) Radio Shack PZM for his overheads. It is of course mono, but he gets by. It cost like $50. It would be better to have a good condenser stereo pair, but for $200 your choices are limited. You could probably find a pair of used Oktavas or C1000's for around $200 if you looked hard enough.
