Cedar point model roller coaster

when I was at cedar point for the 2009 season, there was a model roller coaster sitting in the window of the gift shop that is next to the station of top thrill dragster. it looked like a model of mantis. does anyone know if or where you can get one of these?

They make the coaster car models that you see in the other gift shops too.

Here is the one they had in the window on EBay:

I bought it earlier this year, its pretty cool. Id like to try customizing it at some point!
