That's not too uncommon nowadays, Sparky, as sometimes the only way to try out a keyboard is to order and buy one.
I must say, the BK-9 is a very interesting piece...I'm still waiting to see if our local Long & McQuade brings one in so I can get some "hands on".
I see the seller is more interested in a module, BK-7M...personally, I'd rather have the keyboard version of any arranger.
