Once you have come to grips with how much the data is actually worth to you, I suggest shopping around. There are services that will handle circuit board issues for much less, since no clean room work is required.
I'm not saying it's a $50 repair, but like I said, pick a reasonable number in your head for what you expect and then go shopping. If it's still too much, fine, but don't write the old data off yet.
There are multiple threads discussing this exact scenario on this forum.
Also, there are multiple levels of OCD for data management, I like to think I'm on the more sane side of things, but I still keep track of which content is on which disks, and out of double digit number of disks in my hoard, I would only feel obligated to recover 3 physical drives, and those are duplicated elsewhere. So, would you need to recover all the dead disks, or could you live with recovering a small subset?
