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.
