PJ:
I have a Yamaha RX-V2200 that is about 10 years old, I haven't used it in about 4 years...they sound great for what they are and listed over 2K back in 2002 when they were first out. They can be found on eBay for around $100, which is a great price. Find a pair of Dynaco A25's for under $200.00 and then you have around $100 to find a decent small sub...the total is $400, which leaves room for shipping....
Another thought is hitting you local Goodwills and Salvation Army stores as they get a lot of decent stereo gear right after Christmas...I woundn't count on finding decent speakers there, but many decent receivers in the mid-fi range.
Good luck,
Jim
