I guess I should have mentioned that I am most interested in the consistency it gives on neck tension and the longer brass life will be an added benefit for me. I've looked at most all of them including building one myself and haven't ruled that out. If I weren't an electrical retard I for sure would build one.
What about salt bath annealing any of you guys have any first hand experience? I've read quite a bit on it and have mixed opinions.
same deal on salt bath as flame. you are the variable. with the machine, I just set the time. they all come out the same.
