Yeah, I know a guy who refuses to give up his 850. Heck, I know a guy who buys 700s when he can find them so he'll always have a supply of parts to keep his going...a bit more work than I'm willing to do.
My MX-810 is on it's way out and I was going to get an 880 but I think I'll hold off until I see the MX-780.
