What might one be expected to pay for something like this?
I think I'd be tempted to negotiate.
A couple of years ago, a friend and I were in the market for two electronic instruments. We viewed several before we found models with which we were happy.
Ultimately, my friend decided on an organ we saw at a local dealer, and I decided on a three manual version of a two manual instrument which we saw at the local dealer's, but which he didn't stock. However, the manufacturer could supply that instrument, and also had one which was an ex-demo. So, my friend and I talked with the supplier and the local dealer and made them an offer
considerably less than they had been asking for the new organ for my friend and for the ex-demo one for me. With a bit of negotiation, they agreed to our offer.
My friend received the organ that he saw at the local dealer's. I received not the ex-demo one, but a brand new version of the instrument I wanted at about £4,000 less than the usual price.
I understand that there is a large profit margin on electronic organs (at least in this country), and it is obviously well worth negotiating.
