There are some cheepies that pop up on eBay but they are few. I would suggest an old one from a standard brand (and I have one in my closet, too).
I used to have a Pioneer decoder that I used with my Proceed PAV before I bought a PAV/PDSD pre/pro. My recollection was lots of cables, but I'm not sure why that recollection would be accurate, but it caused me to try a Sony 444ES for simplification. Unfortunately, transparency was sacrificed. The PAV/PDSD restored transparency.
