WOW. When ebay first started I was into buying, rebuilding old COX 1/24 scale slotcars. OF course nobody had seen these things for 40 years. THen when everyone and their dog found ebay there was a huge spike in demand for these. It was the most lucrative hobby I ever had. THen when people started realizing what these things were selling for, everyone started searching their garages and basements. Soon there was ample supply and the prices started to fall.

I wouldn't be in a hurry to spend the money until you have it in your hand. With ebay you never know.

I was thinking of doing the same thing. I have 10 tanks now with my second tiger on route. I love to rebuild them and detail them, but there is a limit to how many I can store. If I could even get half that amount for my rebuilds I would be happy.
