I picked up a corded two speed in a grey box with bits 30 years ago at a pawn shop. Get a cylinder full of cut off wheels and use them on cable housing, slicing off bolts, and notching fenders. I used it once to put a super shine on a stem for my daughters fixie after I had removed the black anodizing. No more battery tools for me.
