I definitely understand all those reasons. That is why I have a bender. Well except helping people. It isn't that I don't want to be helpful, but time at the shop is crazy valuable to me now so I don't tend to help others nearly as much as in the past. Same with tube work for money. Just plan for a lot of screw ups or pony up and buy bendtech. I wish I had it, but now that I know what I am doing I can't justify it. I know it would save me time and money, but I just don't bend enough tube anymore. I actually just got my bender back after letting someone borrow it for a year.
