I am assuming that list of mics are all true condensers? And then there would be a list of Electret capsule mics?
Here is a a question, what about the Karma K-10?
I've been doing some research on this. That list is all condensers that start out as the basic China 797 Schoeps circuit mic. There are some differences. Some of the capsules have that heavy metal front grill. Some of the bodies have more or different vent openings. Some of the circuits have different component values. Some use better quality components, etc...
Like Richard, I've investigated most of the low cost electrets, but they don't appeal to me as much as the gold sputtered condensers mentioned here.
As far as the Karma mic... I excluded it from the list, even though it uses the same capsules, because it's got a transformer in it and the others do not. It also has surface mount components, which are not user friendly for typical mic moders.
I'm getting to the point where I can hardly work on through-hole circuits anymore because of my eyes and arthritis. So, SMT is definitely not for me.
