Zar, I agree, it is extremely disagreeable to contemplate trashing a good bit of $1k kit over the lack over a $50 part. Manufacturers are at the mercy of their laser suppliers and it is obvious that Marantz chose some troublesome lasers, judging from the numerous online comments about frequent replacements. In fairness, it's not just Marantz that suffers from this problem. I would definitely call Marantz's customer service and see what they've got too say. It has been at least six months since I went through my experience with a bad laser, maybe their engineering department has worked out a replacement package that works. (I also wondered if the repair facility I used was simply tired of working on my player- that was its third laser replacement- and claimed they couldn't successfully install the Marantz replacement parts.) As to the Ebay seller's claim of a "one fits all" replacement, I'd be dubious about that one. Marantz customer service can verify the part number needed and you can judge from that point.
