i'm just on the look out for a nice score, the kind i read about here on GJ, to add to my own tool collection
Those scores are the result of luck, timing, and hard work.
The hard work is in the research for interesting sales (like the listing you posted) and the legwork to go out and explore yard/garage sales, flea markets, and thrift/pawn shops. The timing is about getting to it before someone else, and catching the seller at the right time to accept the price you're willing to pay (There are haggling tricks that can be learned, but not necessarily taught. It's a skill). And the luck is finding the items for sale in your area in the first place. It's the
Wild Hunt.
What you don't see listed in these forums are all the bad sales explored, no sales, and bad purchases that it takes to finally score a good hit. We're generally too embarrassed, chagrinned, or angry to expose those to the people we're bragging to.
Take into consideration how many members are on this forum, and how few of them post their weekly finds. They are the dedicated.
The listing you posted is a good start on your search, whether you buy it or not. I may view 20 or 30 listings like that (if I can find them) before I actually leave the house to look at one, only to discover it wasn't worth the effort (or gas), and while I may have scored a few good deals I'm certainly not in the same class as many of the others who post their finds.
Enjoy the hunt, savor the kill. But don't let it get you down in the meantime.
