I was also one of the lookers who did not post. Liked the cooler but had nothing to add. There are a lot of lurkers here that are looking to pick off machines but there are also many useful search tools and apps that could have led many people to that cooler without too much effort. Sorry you got sniped
but in general this board and the people on it are very helpful.
Early on in my collecting, I did what you did with a very rare cooler and almost got sniped by another member/lurker. Fortunately for me, the seller honored his deal with me and did not sell it out from under from me even though he was offered more money by the guy who tried to snipe me. Lesson learned the hard way. Now that I have been around a bit, I typically do what Eric describes and consult with a few of the friends I have made. I don't usually post pictures until the machine is loaded and in my possession.
Don't despair as many more coolers and other machines will come along. Unfortunately, it is often difficult to forget about the one that got away.
Happy to help whenever I can.
