You can get an Onkyo TX-NR717 on amazon for less than the UMC. It has 7.2 preouts and many features found on any midlevel AVR, but not the UMC.
The UMC is a bare bones unit with no video processing, no networking features, no legacy video input, no 3D and very simplistic room correction to name a few shortcomings owners have mentioned. That said, it apparently has pretty good audio performance, so it depends on ones priorities I guess.
Personally, I wouldn't buy an entry level processor of any brand. Too many deficiencies. If all you can afford is 600, I'd wait 6 months and save enough for a Denon AVR X4000. Absolutely loaded and owners rave about it.
