I don't know if it's worth $2230, but it appears to be in exceptionally good condition, at least cosmetically.
So if it plays as well as it looks, perhaps it's worth it?
It looks like it would be a really good one to buy, but $2230 would be a pretty high price for an unrestored 73 Stage in the US, I think. That said, I would expect to pay a premium for a Rhodes in such good original condition. If it were me, in the US, I'd try to get them down closer to $1500. In my mind it's overpriced by about $500.
I would say, in the US anyway, it would be very easy to find a cheaper one, but difficult to find a nicer one.
