I think some of the units listed should have better actual retail pricing than the MSRP. I'm pretty sure I saw the Yamaha unit like you noted listed for $599 at Crutchfield. I'm interested in hearing more feedback on the Denon 1611 unit once it's been out for a bit. Considering their feature set and pricing, it should compete well if doesn't have any quality issues some BD players seem to be plagued with.
Bummer to hear about your Marantz BD player. Is the 8200 one of their first revision BD players? I think quite a few manufacturers rushed their first BD players out the door to compete and most definitely missed the mark in functionality and quality... -TD
