These posts are a good case for saying -"ALWAYS cover up your keyboard when not using it, and not just a cloth (they let dust and spilt drinks through), but a good custom made plastic one. Dust is your enemy!!"

With the costs of some arrangers now, and how amazingly good they have become, you are going to want to keep them for a VERY long time. Dust, tobacco smoke and dirty hands will take years off your keyboards life.

And buy a GOOD flight case if you travel often - cheap padded bags will not stand up to years of gigging, and do not protect well. Don't assume that nothing will go wrong, assume it will and prepare for it and your expensive arranger will keep on truckin' for years!!
