Just returned from an auction with a Delta/Rockwell 33-990 RAS in really good shape (no rust, etc). Paid $50.00. The rear table and fence need to be replaced, and the lower parts of the blade guard are missing, But for $50.00 I couldn't pass it up. I plugged it in, turned it on, and the motor made a nice purring sound as it spun the POS blade that's mounted on it. The only bad parts are... now I have to learn about radial arm saws and it just about uses up all the available shop space.
