I got a black one from Richer Sounds last week for £789.99 with a bit of haggling, a good deal for rrp £1400 receiver!
I'm not bothered about the networking as it's hooked up to a Home Theatre PC, but it's worth a bit extra over the 875 because I believe it has seperate power supplies to video and audio.
Having said that it's not as well built as the Pioner VSX-AX5i it's replacing and the stereo playback isn't as dynamic either, I'll give a bit longer to run in before passing final judgement!
