The thing that bothers me the most about Rock'nRollers is how much room they take up in a car. I prefer the folding wheel handcarts, that fold up flat and can be stored in the smallest of places...

BTW, my keyboard case has handles at the ends, so, once the handcart is loaded (case, cords case, stand and seat, mike stand and monitor stand all in one go), I don't grab the cart itself, but use the handle on the case...

Has anyone seen something like the Rock'nRolla (four wheels) but with folding wheels that collapses to a smaller form?
