Being the happy owner of a QR-25 Quincy bought off of CL for a song, I am biased and will keep quiet about them but if you can afford it, try one of the Quincy, Eaton or IR units. Another good choice are the upper end units from HF at the mid range level (these have Baldor motors and ABAC pumps). Most of the box store units are re-branded CH compressors and, for all practical purposes, are equal if the CFM ratings are similar.
Also check Craig's list for a good used compressor, have the cash handy and buy when a good deal comes along. If it is a 3 phase unit, count on spending $300 to $400 for a 5HP Leeson or Baldor motor (the 7.5HP motors will run a little more) to convert them to single phase. You can also get a rotary converter but it should be rated for starting a compressor motor of the HP yours has. That can wind up costing even more than replacing the motor.
