My uncle has a Dewalt Powershop radial arm saw he's selling. He offered it to me for free, but I didn't want it. He's had for sale on Craiglist for months, and it's only $100.
Something that came to mind is if radial arm saws are even worth anything at all. They take up so much space, and sliding miter saws do just about everything a radial arm saw does except the ripping function and dado blades, and works a lot better in my opinion. I used a RAS when I was in high school, and never really liked it. That thing was a mean machine, and for some reason that thing always lunged forward on me. Anyway... I guess it's really not a tool of the modern day workshop
