Yo DAS:
You can call some major vendors and "price" both units. You might find one vendor might give you free shipping and a price of the "better" Yam that is the same as the "lesser" model.
Or, you could go to a major vendor's store and try each model.
I think if you call the 800 numbers, you might get a deal as vendors are dealing.
Try Google too and specify the models you are comparing.
When you get to the end of researching, call Full Compass and get a price on the model you want. Or, any other of the major dealers.
Good luck.
I know you'll enjoy the keyboard because both of my Yams have been winners.
