So, it looks like most of the "low end" Beyerdynamic mics are made from standard capsule types. Unlike Shure, Audio Technica, Sennheiser, etc, there appear to be no gems here.

I think that is accurate. However, at the prices I paid for these on eBay, I don't feel totally ripped off. I wonder what is inside my MC930's. If it's a Panasonic, I'll feel I paid too much.
I've only actually listened to the MPC 65's, as drum OH's, and I thought they were pleasing (better than some MXL's I used to have). When I get some time, I plan on doing a drum OH comp between MPC 65/MPC 66/MEM 86/MC 930. It will not be scientific by any means, but it helps me understand what I've got in the mic closet.

Don't worry, the MC930 are real condensers. Nice capsules. I havne't taken them apart (yet), but I've seen the insides of the MC833 (XY/MS mic), and those have the same caps.
As far as the boundary mics, I think the MPC66 have a fairly nice omni cap in there. It is probably nicer than the (obvious) WM60. It may also be worth modding these mics. In particular, putting a 4.7k resistor between FET source and ground.
