I once took the hassle of having an EX-1 with two TX cabinets shipped from the USA to Germany. It was fully crated by the forwarding company, weighed in at half a ton, *and* it was shipped in a 40' container -- it was a nightmare. Much to my amazement, the instrument survived that massive journey, and as far as I know, it is still in use today.
The EX-1 and EX-2 are wonderful pieces of art and gorgeous to look at -- the EX-2 is considerably more rare (so I´ve been told), there was one for sale a while ago, priced at roughly 1,500 US$ (with TX cabinet included). I´d reckon something around 2,500 to 3,500 US$ for the EX-1 seems to be realistic but not really likely -- after all, it´s a massive piece of furniture, and only a few people actually want to own something like that (which is a shame as I´d love one of these if I had a spare room for it -- and the TX cabinets are awesome as well).
If you´re looking for a quick (and probably less profitable) sale, you might want to put it up for auction on eBay at a low starting bid. If you want to make sure it will find a good home, try Peter Forrest´s VEMIA auction first (there was an EX-42 up for sale earlier this year).
