Get a Canon or a Nikon. The lens selection is better, particularly on the secondary market. I love my camera but I wish that I had the flexibility of the second-hand market for lenses that the two big boys enjoy.
The older Pentax SMC-FA auto focus lenses for the PZ/SF series work on the newer digital bodies.
The older Pentax SMC manual focus lenses will fit as well.
Remember also that Tokina is now making Pentax's lenses so you shouldn't see any drop-off in quality from what you would expect with a Pentax AF lens by going with a less expensive Tokina.
