Anyone else keep an eye open for old tools? I picked up an OLD circular saw for $20

Pretty cool. My big regret is that my Gramps used to have a little, compact "Mall saw." The attraction there is how light and small it was compared to "every other thing." It was great for light stuff and plywood.

Later in his life, it burned up the motor. Gramps gave it to my Dad and he had it re-wound. When Dad died I ended up with it. However, it was damaged badly in a house fire, and really no way to restore it.
