At the risk of repetition, add me to the ever-growing list of Jerry's admirers. I have a SST gun that decided to do everything wrong and/or nothing at all. Reluctantly I sent it to Jerry after calling him. I described the problems to him, and his response was "I'll fix it and return it to you IN A DAY!"
The day he received it he called me, told me what he had to do, and was in the process of packing it to ship back! Further, he discovered another problem unrelated to the SST, and repaired that also.
Suffice it to say---JERRY IS THE MAN !!!!!!
