Wouldn't this be the ideal solution for you? It also comes in silver and has piano and other sounds for other uses. Weighing in at 12 lbs along with your 24 lbs 3000 certainly sounds a lot better than lugging around any of the 40+ lbs 76 note arrangers out there. It would take seconds to hook it up.

Or maybe you would prefer an 88 note board.

Maybe you'd like the M Audio 88es or 88sx.

It would just be a matter of finding one that you are satisfied with the keyfeel and weight.

What do you think? Have you tried this approach yet?
