the idea is good..for those like me who prefer roll their kb around without a case on a hand truck rather than have it in a case and all their equipment on one roller. but i can see that it is flimsy. SO-- why not take a solid x-stand, buy a couple of good wheels at a hardware store and screw or bolt them on the frame in the appropriate place..then get a piece of metal to make a shelf wide enough for a kb and bolt that on? doesn't have to fold up, since only needs to be maybe 8 inches inches wide. that should be more solid and durable than the trolley they are selling. I'm not that handy but i might try to put something like that together..maybe one of you is talented in that way and can come up with a prototype we can copy or even buy from you..???
