I don't think digital recievers was mentioned. So I'll add that the Panasonic digital recievers seem to be a very good bang for the buck. The XR50 or XR70. The most celebrated Pansonic digital seems to be the XR45, which is hard to find now. Also the JVC digital lineup is getting good reviews. The RX-F10. Most of these recievers are quite inexpensive. I auditioned the Pansonic XR-25 while my Outlaw 1050 was in for repair. I was quite amazed at how well it compared to my 1050.
