I've used Pentax for about the last 12 years, when I first go into photography. The ZX-50 was my first "good" camera. A year and a half ago I finally made the jump to digital with the K-10D. The main reason I stuck with Pentax was that I have a couple decent lenses and did not want to have to buy all new lenses for a Nikon. Now that I've sent my K10 in for warranty work for a second time in about six months, I'm questioning my decision to stick with Pentax. There are some good prices on D80s and I'd really like to have a camera I can count on. Not that there are any guarantees I know, but this experience has soured me somewhat on Pentax. Not to mention there's a lot more lenses out there for the Nikons. Any thoughts?
