What issues are you having with the Sapphire? I just bought a 960Q, could you trade up to a different model? I know they will only give you what you paid for the machine for one year but if your issues have been documented I would certainly give them a chance to fix it with a different model perhaps. I've never had any trouble with my Vikings and I own 4 of them. I do remember from my days of selling them that the 835 did have some issues.
