I 've owned the 2900 and 2910(2 of them).Both 2910's were sold.Even though I rarely use the 2900(it serves as a spare backing up a Pioneer Elite DV 79AVI)I cannot bring myself to part with it.It's built like a tank and I found the video performance to be better than the 2910.The 2910 is a much smaller,lighter unit.The SACD performance of the 2900 is very good and it does a nice job with redbook as well.The larger, heavier 3910 would be of interest but I have never had one.
