I have a 775 also and love it. I printed my first 8 x 10 on photo paper a few weeks ago and it looks great.

At CompUSA I got some deal where I pay $80 a year and I could literally destroy the camera on purpose and they'll replace it. I specifically told them I'd be bringing it float tubing and if I dunked it in saltwater and it stopped working would they repair or replace it and they said yes.
