I am trying to decide on a used pro gun that I found for $350 or a Basic gun kit from Eastwood for $129. I just got 2 ovens yesterday a big cooking one that was used at a school so it is a little larger than normal and a small toaster oven type. But now I can’t decide on the used pro gun (no warranty) or the basic Eastwood starter kit. So what is the difference in the guns as far as quality and shooting goes??
