My best was a Sega Genesis Model 1 lot that came with a bunch of sports games. I won it for $10 or something. Not surprising since no one wants sports games. But it was a gem for me because it was an HD Genesis and came with the composite output cable, all the metal peices for a Model 2 Sega CD and the Sega CD RAM cart.
Best deal I ever got was a Sega CD RAM cart for $40 flat shipped from China. Don't worry. It's legit and not a pirate clone.
a good deal I remembered recently was a £10 "mystery" box of NES games. Picture was a fairly beat cardboard box with a bunch of games dumped inside it, bought it and was pleasantly surprised to find it had a copy of Aladdin for NES. Game is crap but it paid for the bundle 5x over
Clock Tower 3 E3 2002 promotional t-shirt, only cost me a dollar and it was still in it's sealed bag and the like. Would've been an even better score had the guy also had the digital watch and it's tin as well to go with it, but he had no idea where it was from and even had a look around to see if there was the watch and it's tin floating around in the box of stuff he randomly picked up and found the shirt in. So far, one of my best scores from eBay. The only other ones would be getting some official Final Fantasy merchandise for fairly cheap (as auctions), also including some plush toys - I wish they had made a Moomba plush that was more common instead of the tiny little prize machine one as I'd love one to have with the Cactuar, Tonberry and the multiple Moogle, Chocobo ones and the Goblin, Carbuncle ones and the like. Oh. Can't forget the PuPu/Alien thing that I keep forgetting it's Japanese name.
