You can try to clean it yourself with great care if you have a *ist D, DSx and K10D which the focusing screen in them are detachable.
For the exact instruction and steps, go to the Pentax Imaging (USA) website, search in the manual archive for the Pentax's first AFSLR (well, not count the ME-F of course) named the SFX, then you can find the detailed instruction there.
Do remember to handle with great care. The procedures are not quite difficult, though.
After you can detach the screen, you can clean it with a air-blower and micro-fibre cloth etc. as you like. The screen is made of soft plastic, so, cleaning it gently only!
