building on a budget--looking for amp advice


I'm trying to put together my friend's first sound system for around $500 or less, consisting entirely of decent used equipment. I've decided that the old B&W 600 series is a good bang for the buck, esp for a newcomer, and if they can be found cheap enough. I found a pair of 602.5 S3's (not the ideal speaker, but cheap) for less than 200 bucks in mint condition, and I am now trying to find an integrated amp or receiver for $300 or less to go with them. I'm partial to Rotel, as it would be an easy match for the B&W's. However, I'm open to advice. Currently there is a Rotel RA-985bx for sale at $250, but I have no experience with this integrated amp--can anyone tell me if this would be a good match? Any other advice is welcome. Thanks a lot.

any specific models in particular? I've heard mixed things about some of the older NAD models.
I would stay with Rotel. I have B&W 602s3 speakers and have used: Arcam A90, Nad 318, Rotel 1062. The Rotel sounded the best to my ears. Rotel is known to have a nice synergy with B&W speakers..... The Arcam and Nad are both nice amps also,I just think the Rotel would be a better match. NAD and PSB speakers would be another suggestion?
