Thanks to you, Craig Newmark, I got $200 for my radial arm saw (more than I hoped!), and it sold within 24 hours.
The guy that bought it wanted a second saw for dadoing shelving boards, meaning the alignment issues I had with this saw shouldn't be a problem for him. Especially if he leaves it in the cross-cut position.
Now I have a place for the new table saw. I did some test cuts on it yesterday and they were gorgeous.
