Correct onh being expensive, the one built for the 11K scope that can take rack width equipment can sell for over $150 USD. A friend paid $200 for his !!!! THe older carts are not that expensive.

Has anyone recently tried shipping a Scope-Mobile by Greyhound bus? Used to be they would accept them without being packaged, just with a tag, and the price and handling care were fine. I did see
