Craigslist, my man. Now is a most excellent time to be in the market for tools of any sort.

Desperate people need money, and you can help them out and get a deal at the same time.

For a vise, look for something old and American made. They usually clean up easy, simple machines.

I purchase nearly all my tools on CL. Look for reputable brands in good condition. They'll last.

If you see a deal thats too good to be true.......... it might be legit.

I've found that CL is a place that that axiom can sometimes NOT hold true. Of course, inspect any potential purchase carefully. Caveat emptor.
