I was on my local Craigslist shopping for a smaller table saw. Ran accross a Rockwell 10 inch contractors saw. Table is pretty rusty, surface rust it looks like. The rest looks pretty good, got a really nice rip fence. Has not ran for 6 years, seller does not know much about it as it belonged to father in law. So is it worth $150 if it runs ok and arbor bearings are good? Or I can offer less and see what happens?
