Actually, I think the last one on here sold for $6,500 ... I was *that* buyer . There was another one for sale around the time that I bought mine that sold for $6K w. invisiglass (it was in Kentucky ... I missed it by one week ). I could be wrong though. Trek LEs are all over the place price-wise.
I'm still happy with the one I bought and have zero plans to sell it anytime soon and zero regrets paying what I paid for it (I am a *cheap* bastard too ) ... in fact, my 1.5 year old son just "played" his first game ... he pressed the start button when it was on, reached up, and hit the "punch it" button. For that reason the game is priceless to me (I even snapped a picture of him "playing" his first pinball game w/o my wife or I holding him ). Come to think of it, the first pin he ever touched was our Firepower. I think we have a new Steve Ritchie fan in the making!!!
