I would not hesitate to go with new aftermarket. I have bought at least a dozen or so and never regretted it.

As for shipping I'd build a plywood box with extra room around the edges 2" or so and then fit bracing inside made from .75 inch styro foam and fill the voids with "popcorn". And screw the sides together.

But before that I'd go to the glass shop and have the new aftermarket glass installed.
