James,
I have a t770 purchased a year ago. Great update to the hp500 previously had.
Faster printing, better dpi, large 130ml ink supplies, with additional Matt black &grey cartridges. Comes with a hard drive and Ethernet port. Quite a bit larger than the old 24" 500.
Has worked fine with 15. I am still on os 10.6.8 but should be fine w/ lion.
Did not really explore canon or other options.
