What is the best receiver for me?


First of all I think my current setup sounds good, not great but good. Here is what I currently have:

Receiver: Mitsubishi M-VR400 Pro Logic Receiver
Front Speakers: Mission M73
Center: Polk CS-100
Rears: Bose Cubes
Subwoofer: Sony SAWM500

I am pleased with the setup, but I am ready for an upgrade. Knowing this sounds good to me (the Bose will be the first speakers to be upgraded!!) what is a good receiver that offers the following:

5.1-7.1 surround
Good sound processing for theater (up to date DTS, DD... does not have to be THX)
2 Channel Stereo
On Screen Display
Component switching (minimum 4 AV inputs)
Component video is a plus, but S-Video inputs will be ok
Ability to Bi-wire my front speakers is a plus
Under $350 new or used!

I am looking into Denons the 1803 is catching my eye, but is there anything else out there that might be a better or alternative choice to look into. I do not need a super high end system just want it to sound good and be easy to use. Also something that is reliable, my Mitsu has served me well for something like 6 years now and still going strong. The main reason for upgrading is to get something with component switching and better video inputs. (my mitsu only has 2 video inputs, one for TV, and one for VCR)

I think NAD makes an excellent product with a high price/performace ratio. Some of their receivers have preamp outputs for all channels, and I use a separate power amp on my front L-R Vandersteen 2ce's, and the reciever's internal amp on the center and surround sound channels.
Yep, Nad would be good. You might also check out outlaw audio's receiver, I don't no much about it's features but a lot of people say it's a keeper.

What about the Panasonic Digital reciever? I have been hearing good things about these guys. I havent heard one yet. You can buy one cheap at JRs music world online.

The Denon is a good choice, but so is NAD, and Outlaw.

You could also try a search here at A'gon for old threads in the forums. You can find a lot of useful info in the archives.
