Too bad, that looked like a great price on an excellent vise....

Chalk it up to experience.
I’ve said this before on this thread... If you are looking for an excellent price for an excellent piece of equipment on C/L, you have to be patient and spend the time checking the listings several times a day. If that isn’t fun...you know...thrill of the hunt... just settle for a decent price on excellent equipment. Or a low price on inferior stuff.
Fast, cheap, high quality...pick 2 out of the 3
Here’s a tip. Cultivate friendships with people who like to search for deals and have them email, text, or phone you when one pops up.
One of my personal best stories is the one when our mailman told my wife that there was an old vise in a dumpster a few blocks from our house. After work I went over and grabbed it.
Sure it was rusty and seized shut. But it was a Reed 31. I soaked the whole thing in Evaporust and it now sits all cleaned up and operational on a shelf in my basement “vise room”.
On this thread I have picked up deals posted here and have tipped off others to deals they have grabbed. Just don’t post a deal that you are on your way to grab asking if it’s a good price. You might get swooped by a lurker.
