I think this is a case of caveat emptor. The UX-1 is an old player and anyone buying a player of that age is taking a big gamble as regards the continued functioning of the machine, and the laser in particular. The fact that the player was modified is self-evidently going to cause problems in terms of it being serviced by the manufacturer. Really, it is up to the buyer to be aware of those facts, but it never does any harm for the vendor to point those things out to the buyer for the avoidance of doubt in the event that a problem arises. Its unfortunate that the SACD pickup failed so soon after purchase but (certainly in Europe at least) it is at the vendor's discretion as to whether to take the machine back out of goodwill. That is based on the description above that the machine worked perfectly before and (albeit briefly) after it's receipt by the new owner. There appears to be a laser assembly for the player for sale on ebay at an affordable price. Lastly, I would ask the Esoteric service agents whether there is actually a spare part available (independent of the question of whether they would supply it), as there may very well not be.
