I and others have had really good experience with the Foxconn C51XEM2AA; it was one of the best AM2 boards back when it came out. It's currently 159.99 at ZZF and there is an $80 mail-in rebate offer that will bump it down to $79.99; however, that expires on the 9th. I've got mine running fine at 3.0Ghz just by bumping the multiplier up to 15, and I am going to work at going higher once my new tube of Arctic Silver comes in the mail.
It hasn't given me any trouble in the year or so that I have had it. The DIMM slots are kind of close to the CPU bracket, so make sure that your HSF won't have any problems with that.
