b-stock generally carries a lesser warranty than the original manufacturers. i didnt see any video differences up the line of denons until i saw the 5900, and it is just too much for a dvd player (esp. since it was marginally better at best, for video i mean). not needing sacd/dvda support (still can/do get my music for free, yeah internet!), i got the 910 and am very happy with its performance. my only qualm before buying it was it looked kind of cheap and it is pretty small, however those worries were unfounded, and it is excellent. if it was my money id get the 2200 (bstock if you want), and replace it with hd-dvd and move it to 2 channel or whatever; sell it. better yet, you could demo them and see for yourself that you are tossing your money out the window... perhaps you would convince yourself that you arent...
