I bought a XQ-2 from the refurb store, and I'm pretty happy with it. The shots look pretty good to me. I have a half dozen comparative shots in the X10 and the XQ-2, but I have not uploaded them yet. This last week we've been with my son's family, and took quite a lot of shots with both cameras. The XQ-2 is really nice, very small and compact so you can always have it with you. The f/1.8 lens is very nice at the wide end, but indoors I found the lens very slow at the long end, and switched back to the X10 to keep the shutter speeds faster.
Edit: don't forget the discount codes...
