FWIW, we got my in-laws the Sony S5100 model for Christmas this past year. I think I paid like $90 for it at Best Buy. They had an old Onkyo DVD player that was dying. The Sony was a huge step up for them...slim profile, and I would say it had excellent picture quality on their LCD TV. Very user friendly interface, similar to the PS3.
I currently own two PS3s that I use in my two HT systems, and see no reason to upgrade right now. 3D doesn't interest me much.
