I'm having a problem where my C330 skips a frame every so often, which is visible at 1:40 or so in this video:
.
Bill Rogers of mamiyarepair.com has told me that due to his current repair volume he's not taking TLRs for repair. He recommended Precision Camera Works in Austin Texas, but there are plenty of recent horror stories about them online with people never getting their cameras back. Bob's website says he's recently injured his hands which doesn't inspire confidence either.

So: does anyone have a line on a good tech for a Mamiya C330 repair that isn't one of those two?

Check the light seals and the latching of the back, because the latch is connected to the double exposure prevention system.
Check that the lever that pushes down the release on the lens is in the correct place.
See if using the front mounted shutter release instead of the side one changes the issue.
If the lens board isn't in exactly the right place, it can cause issues.

Thanks, I'll check both out.
The latching of the back is a little weird, as shown nearer the beginning of my video. Note that you can press on it as hard as you want and it won't latch further than that. It has a lot of play (but with a fair amount spring pressure holding it out). I did wonder if that could cause a problem, but I also don't know why it's happening or how to fix it.

The shutter levers (cock and release) are both in the right position. I'll have to test if the front shutter release behaves any differently. I use both releases during normal use, but I haven't noticed whether the problem only occurs with the side one.

A slight misplacement of the lens board can cause problems with this - so check for any bends or deformation in that entire system.
