You can't go wrong with the Bottlehead Foreplay. They have an excellent reputation, a strong following and good resale value.
Cary AE-3's come up from time to time for $300-350 used. They have a tiny footprint and sound very nice. I had one for a while.
The Eastern Electric MiniMax gets rave reviews and goes for $500-600 used. Six Moons reviewed it a few years ago.
Personally, I don't care for passive preamps matched with solid state amps. If you had a tube amp, I'd second the Promitheus suggestion in a heartbeat. For $300 used, they're impossible to beat.
