Need a suggestion on some Bodywork Tools

i havent used the harbor freight stud gun but if it has a warrantee it should be fine. when i use nails i like a t-handle instead of a slide hammer. the slide hammer is fast but its easy to over work the metal and then you get oil canning. with my experience with body work its more the person not the tools. as long as the tool is there and you know how to use it you can do great work. sometimes nicer tools make it easier but not 100% neccessary
