One more thing to consider is the sales tax factor. In my state of Georgia there is no tax or state transfer fees on a casual sale. That is one from one person to another, not involving a business. however if purchased from a dealer, even out of state as in my case you pay the tax. I know this is as dumb as sh*t, but thats how back asswards the morons running the state are.
So, with that said, a purchase used from a person might make more sense than buying a new 11 even at a price of around 13k if you dont pay the tax.
But if tax or fees are collected regardless of from who or where you buy it, I say get a new 11 for high 12's to 13 range. If its a bike you will keep for a long time the small additional amount paid to buy new really doesnt matter that much.
I always look at a brand-new used one before buying a brand new new one but it seems to go the dealer route all of the time. Also as crazy as it may sound, I dont like taking off on a two wheeled 150mph gyro rocket that somebody else has monkeyed with.
Seems like getting a bike like the 14 new for 13 is a good buy.
