Clearly, this is going to be a really hot topic. But for the sake of the archive, I'll post this update.
I got my Pentax K>EOS adapter. The K T-mount I had fits loosely on this too, so I may be beginnning to understand why I got it so cheaply from a surplus site (bought "pentax," got K instead of screw mount). I still don't have the K-mount lens I ordered although I expect it shortly. In the meantime, I tried to mount a Praktica B lens onto the K>EOS adapter, and it will not quite mount. The B mount flanges appear to be just a fraction too thick.
