Creek also makes a decent phono preamp in this price range, and there is also a small unit from England called the Gram Amp which has gotten positive reviews. However, if your budget will stretch a bit, I'd explore buying a used Lehmann Audio Black Cube. The earlier versions of this phono preamp were quite highly regarded by a number of reviewers, and can be purchased used for around $300-350. (The newer SE version, with the expanded power supply, is a better unit, but costs about $250 more.)
Honesty compels me to say that I am not totally impartial here. I own the Black Cube SE, and have been extremely pleased with it. However, I think the Black Cube is better suited for use with either moving magnet cartridges (3-6 mV), or high output moving coils (in the 1 - 1.5 mV range).
