Prices have shot up quite a bit lately. A Europa sold last week for $3600(US) which is more than I've ever seen a used one sell for, it use to be you could get a Series 1 for around that price. But I do think I read somewhere that Alembic's prices have gone up which could be effecting the used instrument market. I may be attacked for saying this but I will anyway, a used Alembic is a good invest in times like we're in now, I don't see Alembic bringing their prices back down so they will only sell for more, but buying a new or custom Alembic is not so much...like the Tributes in eBay for roughly $10,000 I doubt if someone bought it they would be able to get that back out and with buying a custom, say you spend $15,000 on one made to you're liking, you may only be able to sell it for about the used market value of that model depending on woods and such of course.
