I've been busy selling stuff on eBay so I guess that I had to balance this by buying something as well!
I've just bought myself a new/secondhand Pentax K10D + a Pentax 16-45 mm f4 zoom lens. The seller had only taken a couple of hundred shots with it and then decided to sell it on eBay. I paid a decent price for it although I think it was a good price and it was significantly cheaper than buying a new one.
I'm still playing around with it but my first impression is a re-enforcement of what I have read about this camera. You HAVE to shoot raw and process the images with Adobe Camera Raw. JPEG's out of the camera are seriously ***p. Raw images processed with ACR are seriously good. Its chalk and cheese.
People say that its a heavy camera and compared to some lightweight digital camera's maybe it is but actually its a little lighter than my Nikon F90x (N90s) and the Pentax 16-45 f4 lens is WAY lighter than the Nikkor 35-70 f2.8 lens that I used as standard on the Nikon so overall I don't consider it to be a heavy camera at all.
