Is this a ship to you deal or can you go there? You take some risk if it is shipped to you, sight unseen.

Be sure it is not damaged and be sure everything works. You might call Roland on the warraty to be sure it is true.
I have bought open box stuff, no problem...it may have been a return also.

I would look carefully...sight down the keybed too,make sure nothing is warped/bent.
