I sold one through Craigslist for $35 a few years ago, an old Craftsman or Monkey Wards, I've had both. Those old units were made pretty cheap and were under powered. It was impossible to set them up to make consistent, accurate cuts. And they are dangerous. For me, they weren't worth the space.

My Delta contractors saw and DeWalt compound miter saw do everything I need, accurately and with more power.
