Just got the R300 cheap (microcenter.com 20% off sale right now).
Like the 925 before, works just as nicely printing directly from the
digital camera cards w/o a PC, and the prints come out looking great.
Quieter than the 925, a touch faster, and nice direct-to-CD print
feature is added.
Solid as a rock, works 5 minutes out of the box and after the
brain-dead-easy CD install, and no problems at all. Certainly expect it
to run just like the 925 before w/o problems.
Highly recommended for a nice photo printer with direct-card print
capabilities.

Don't know about the i960, but the i550 here has been running fine for
ages as well, so expect the latest models to do well.

Keep in mind that 4x6" Epson Premium Glossy Photo Paper 100pk is $15.
Canon 120 pk. of photo 4x6" is about $25.
That alone means your 4x6" prints will cost more based on paper alone.
(I've looked, everything's more expensive than Epson for 4x6" photo paper.)

Quality? email me if you're in the USA and I can mail out some samples
from the R300.... but basically, looks great and I'd buy another w/o
hesitation -- really great glossy photo prints that look 'better' than
the semi-glossy Kodak Ultima film prints I've made from my local lab
(and the others who've seen both sets of prints agree). YOu can really
make better-than-film-prints nowadays.
