Best Home Theater Processor Used 1K-3K Range

Hi all,
Looking for a Home Theater Processor that has an HDMI input and does all the latest formats, DTS-HD MA 7.1 etc, that I can pick up used in the 1k to 3K range. Preferably no speaker outputs if possible. No mass market crap, ie Panasonic, Sony, etc. Can anybody suggest anything good that I could scoop up on Ebay or Audiogon? I currently have a modded Oppo BDP-103 and am using all analog outputs to an Onkyo preamp and am looking to upgrade sound wise. I am also looking to upscale 5.1 sources to 7.1 which the Oppo can't do.
Thanks
