Cool idea for a club. There are enough common issues with these pins that it is nice to have a common place to go for tech help.
I own a Special Force, and it usually works for a few months before something breaks. It was out of commission for quite some time due to the solenoid expander relay. It worked intermittenly because of cold solder joints. I had never done board repair work before, so I was afraid to touch it in case I messed up my only semi-functioning relay board. I finally found a new one from Marco Specialties and then decided to try my hand at repairing the old. I'm happy to report that I repaired it successfully and gained a bunch of confidence in doing so.
Anyway, happy to be a member here.
