Good luck with the P6 and K60.
It's not the body cost, it's the cost, range & general quality of the lenses and other accessories that make the system attractive.
I love using my P6, regardless of whether I'm shooting with the CZJ 50, 80 or 120mm lenses. Next items will be either a 30mm or 180mm.
For the brighter screen, I had one fitted from a Kiev, with microprisms. This makes focusing in dim light quite easy, even when the 120mm is on a short tube (ideal for baby portraits!). I also got it CLA'd and a film wind indicator fitted (as a precaution, I'd never had spacing problems).
Learn how to load the camera properly and you should have no frame spacing problems.
Look forward to seeing your results.
