4. Here's an assorted collection of tools. The grinder came from my dad's house a while ago, when we were 'bagging a Cadillac. I never gave it back (sorry, dad). The die grinder on the right has seen many projects and costs about $80-$100. The impact gun is from Sears and is part of its Professional series; it costs less than $200. Steve was nice enough to let me borrow the Matco body saw. He bought it new from the Matco truck for about $160-$180.
