Source for Chinese SDC capsules?

Does anybody know where I might be able to source a decentish (I'm thinking 10-20) number of cardioid small diaphragm capsules of the Chinese variety? The ubiquitous ones that you see on MXL 603/991 and other variants, the CAD GXL1200, Apex 180, Monoprice 600700, and etc.

If anyone is interested in why, it's because I now have access to a lathe and I'm interested in trying my hand at modifying the capsule housing. I figure I'm going to need a few for trial and error and to see what works best.

Thanks!
Rod

I have a bunch of SDC capsules (brand new) pulled out from MXL 990 - 770- 603 - 550 - 551 .
can sell for 10 euro each
