Piano truck choice?

[Susan Kline]

Hi

The Newport Arts Center has a Kawai grand in their front foyer, roughly 
5'6". The director has asked me to figure out what sort of truck they 
should buy for it. He says he doesn't want anything "clunky looking" but 
they need something to make the piano easier to wheel around on the (firm, 
thin) carpet.

Any suggestions? It's not something I've done before.
