Bump, price is now €85 and I'll take a Movember donation of €5 in lieu of shipping. So you can upgrade your camera and have the feelgood factor of donating to charity

In support, I love my Katzeye screen. Brilliant for manual focus in particular. Optibrite treatment works really well too. Combine with the OME 53 to transform your viewfinder! If I didn't have one already I'd buy this.....they're a lot more expensive new.

Does it affect the metering?

Seemingly it does according to some. Must admit that I have not noticed any glaring metering issues personally. So Mike, the answer is yes it does but it did not affect me. Saying that I have used this in conjunction with a 50 f/1.2 for low light band stuff and I did not have any problems with spot metering where it seems to cause most problems.

this is from their site:

The KatzEye™ focusing screen for the Pentax K-5, K-5II, K-7, K-30, K-50 and K-500 shows only a very slight effect on light metering. In our testing, the KatzEye™ screen tested within factory tolerance in nearly all situations. The only exception is when using spot metering with lenses having apertures of f2.8 or smaller. This combination may produce overexposure, so it is advisable to use either center-weighted average metering or multi-segment metering to preserve accurate meter response when using small aperture lenses. In the event that spot metering mode must be used with a small aperture lens, it is advisable to set an appropriate exposure compensation by reading the histogram of a test shot. Approximate exposure compensation values are as follows*:
