Congrats to the OP. That's a great deal.
Some of the best deals I've gotten make me feel guilty or sad or both. Sometimes I feel guilty because I feel that the seller didn't really know what they were worth and that I might have been taking advantage of them by not saying so.
Some of my very best deals came after the owner died. The family just wants to get rid of the stuff and could have gotten more if they had just known more. I picked up an MFT/3 set (minus rail) with leg braces for, I think, $150 like that, along with a bunch of other stuff at similarly low prices. The guy was in his late 30s and died of cancer and his family had too much stuff to deal with - so theyjust looked up retail prices and made guesses as to what the stuff would sell for, not knowing that in my neck of the woods Festool stuff sells at much less of a discount than used tools usually do.
I also picked up a full Incra LS router table setup, complete with the stand, positioner, Wonder fence, insert plates and set of magnalock rings, router, and a whole whack of Incra accessories and stuff for $250 from a widower and her son.
Sometimes when I use the MFT or go through the Incra I see the previous owner's hand writing,or careful packaging of screws, and I feel like their ghost is there. And I feel bad that maybe I should have offered more money instead of taking the deal and saying nothing. Sometimes I tell myself that if I had known the circumstances around the sale before making the trip, I might have acted differently.
And yet tomorrow I'm going to go pick up what I believe to be another great deal.
Confessional over. Sorry for the downer.
