What speakers are you going to be running? How big is the room? The PM7200 new is right around $500 and has plenty of power - rated at 95x2, but a review rated it to have actual output to about 105w.
New, the C320BEE is $399, but you can check directly with
www.yawaonline.com (e-mail them) and see if they have any deals on them. They sometimes have promotional deals going on that are not advertised. Again, don't let the low power fool you, this thing has plenty of power and unless you are going to drive some power hungry speakers, 50w should be enough. Next step up is the 352 at 80W and MSRP $599.
Cambridge also has the 640A, which is about $520 I believe. I really like the looks of this guy, but it didn't sound much different from my PM7200, so I kept the 7200.
