There are bugs and problems some people have with the Kronos. Some of the problems show up randomly and surprise the player at the most inconvenient times.
You could literally play the used kronos for an hour or more to test it and have it work fine and then find it doing strange things a few days later and then that stops and shows up again unpredictably.
The problems can be worked out but i think a new keyboard will have a warranty to cover any repair cost.
And you could get lucky i guess even if the used one has problems but only if the repair cost is still less than the savings from not buying the new one.
If you can afford the new one and you value the guarantee of the warranty over the savings on cost, then the new one is the one to have.
The used one could have extra sound sets bought and installed and its not hard to check. You could spend a significant amount paying for extra sound sets, so it may be better to get a new one that comes with some bonus sound sets preinstalled. Some sound sets cost upwards of $500.
Piano players normally like having the varieties of Grands like the german and Berlin Grands. Look up what sounds are installed on the used and see what it cost to add the kronos 2 bonus sound sets. Cost assesments. Maybe you dont require much anyway ?
Any way, if you are open to my bias, its always a better guarantee to get new ,because the factory is obligated to you having a perfect running rig for the duration of the warranty.
I dont mind having problems to work out any way,,thats when i learn the most about the complexities of kronos. Still, i got a brand New kronos 2
Its only with cell phones that i always go cheap or used because of personal issues like dropping it in the rain puddles, toilet or all them other places i have sacrificed cell phones.
