SFBayArea: I can commiserate. Purchased an LG Spectrum a few years back. Excellent phone. I never ever buy insurance for this sort of thing. I feel it is a rip off and don't bet against myself when it comes to consumer electronics. Generally, for items I think might not be covered under warranty for long, by paying with AMEX, I have a years extension to that warranty...
I was distracted one morning going out to the car, and putting out the trash for pickup. Put my phone and lunch on the hood of the car... Got all the other stuff done, was distracted, got to the car, pulled my lunch off the hood. Drove off oblivious to my mistake.
Got up to speed about 50MPH, and the Spectrum became a lifting body. I saw it fly off the hood, over the windshield, hit and bounced on the asphalt.. I had a silicone case on it, and it was flipping nicely, perfectly and rapidly, corner over corner, making its way to the side of the road... until I saw in my rear-view mirror, a car following me take the joy away..
Well, I had to purchase a new one off eBAY for a few hundred, but, the first one, I had gotten from Amazon for maybe -10dollars (yes, I was paid to get the phone)... So in the end, I did much better than had I purchased insurance and paid a deductible to replace (if you can in this scenario - I don't know), because the phone cost me nothing, and only a few hundred to replace.
And yes, by purchasing off eBAY, the phone did not have any form of warranty.
The point is - if you are going to get it repaired, do it right and get the full combo of pieces, otherwise, just go ahead and source another. Only you can do the cost-benefit... And it may be worth your effort to purchase the whole assembly and try it yourself. Don't know your skill level - but as others would say, it's likely not to go well.
We live, we experience, we learn. We move on. Sometimes we optimize some problems to save money, and sometimes, things happen that negate that effort.
