Anyone have some advice for RB shutter repair? KEH is now on a "one-price" level, $180 + shipping for any MF lens with shutter needing service.

It's a 180c, when triggered off-camera it makes the appropriate "thunk" but the iris & shutter don't budge, they just stay wide open.

The glass is in great shape and I hate to throw stuff out... and I just got a really clean replacement from KEH for $65.00. I saw the thread here on disassembling the 180, I might break down and try it. I hate to throw stuff out, especially a nice clean example like this one. Good chance I'd just destroy it trying DIY surgery.

Hopefully there's a forum member who enjoys messing with such things? Thanks for any ideas.
