I too am interested in the Denon 3800, if you wait a few days, we should know if the Firmware update becoming available soon will successfuly modify your standard 3800 from the stores to multi-region, PAL Prog Scan and various bug fixes.
We need to have some kind souls to perform this update and test if the digital artifact and Chroma problems have been resolved.
In short, dont part with your cash for a short while yet!
