I would stay away from the G61 (without room correction). That's just an opinion, but they were never around for that long and, consequently, resale may be difficult. I would only get one if you can't afford a G61R or G68 and *need* 5.1 analogue inputs. If you don't, as posted above, the 568.2MM is the way to go...
