I could part with a couple of mine. PM me, and see if we can work something out. I'm not really motivated to get rid of them yet, but let's see if we can work something out.
I've got 3 pin-locks available for trade. My setup uses ball-locks and I dont' really want to purchase additional parts to convert it to a ball/pin setup.
Let me know if your interested, and I'll send some pictures.
