well now you're making me wonder, I thought I had convinced myself I needed ak37. Working with crappy tools, having them break, and buying tools twice will kind of annoy me. One of the reviewers said some of the stuff is slightly off on sizing on the $33 kit. Plus I checked the shipping on it and it's $16, versus free. So the Park set is $170 more. How many tool replacements would I have to make to reach that $170, while suffering with s*** tools? Hmm..
