Background: Car is a 2001 Boxster S manual. Over the winter, I did the IMS, RMS, and clutch, and changed the transmission lube. When I got it back together and started it, I was getting a noise from the rear of the car. Here's what it sounded like:

I ruled out all the engine-related sources, so figured it must be in the trans/clutch. After a couple of cycles of pulling the trans and checking the clutch/flywheel/fork/slave cylinder/release bearing/every other damn thing, I couldn't find the problem, so I took it to a trans shop. They narrowed it down to something inside the trans. Here's what it sounds like turning it by hand on a bench:

But they aren't equipped to rebuild this trans, so their suggestion was a used trans, but those aren't cheap and you never know what you're going to get.
I've accepted that this is going to cost me a good chunk of change, but I want to make sure it's done right. So, what do you guys suggest? I'm not averse to boxing it up and sending it someplace, but something local (southeast Michigan) would obviously be preferable.
Thanks!
