If you could find a local recoatung business, the last one closed a while back, it will cost you likely minimum of $500 plus shipping to recoat your old mirror. And you will be no better off, quality wise, than whatever figure was put on the old Lightbridge.
Shop around is my advice. Even if you have to adjust the primary or secondary slightly, a higher quality mirror will be worth it, imho.

How do you know the quality of the old one? I suggested testing before deciding otherwise you really don't know the quality of the mirror you may discard.
