I have a Pentax MX and a Pentax K1000. I would like to be using the MX, however there are heavy cleaning marks on the focusing screen. Where can I buy a replacement focusing screen? I would prefer not to use eBay if possible. Is it possible to take the focusing screen from the K1000 (or any other SLR) and put it in the MX? Thanks in advance

Try KEH. www.keh.com They have an SC-1 (the standard screen) in EX condition right now. Their computer auto-complete converts SC-1 to Soft Cover-1, which can be confusing, but if you know that, you're OK.
Screens from the LX will fit just fine and are less grainy and brighter. Their extra brightness will probably throw off the meter slightly though, which can compensated for on the ASA dial or by getting the meter adjusted. LX screens have similar numbering schemes to MX screens. For example, an LX's SC-21 is the same type as an MX SC-1.
I don't believe the MX and K1000 screens are interchangeable between the two models. In fact, the K1000 has a fixed screen, and you will need to remove the top deck to remove the screen.
These days, you'll probably have to go to KEH or another third party to find a screen. The MX has been out of production for a long time. I first bought this camera in 1979.
