I think I would want to know the serial number before I bought it, especially at that kind of money.
Crazy prices, although to be fair it's basically a brand new instrument from what I can see, maybe it's the only one on eth planet.
I would never sell mine (unless I was dying or something and I wanted the money to give to my kids) but I do wonder how much I would get for it. It's the wrong colour and signed by MK, both factors which could end up lowering the value.
