Pat, look at the carts on the site http://www.kart-a-bag.com, or telephone them toll free at 1-800-423 9328, in Joliet Illinois. At least 25 years ago I got an aluminum fold-up cart, model Continental 500, made by this company and it is still performing just as well. I got it at a local large department store, since they have many dealers around the U.S. The site does not seem to have ths picture of this model right now but ask them about it. The cost was very reasonable. When using it for a lever harp (in its harp cover, of course) take along some sort of elastic strap with which to secure it on the cart. When the cart is folded up it is roughly 18 inches by12 inches and very lightweight.
