Glass M/W plate

It finally happened, but our microwave plate, the one that rotates inside, broke in half. They "seem" to be standard, anyone know where there are replacements available? Better to replace than junk the working microwave.

Thx.

Used to be stacks of them at Barbara's Bazaar but I haven't been in there in quite awhile.

I have never been to B's B... might have to now.
Was not going to go the "new" route or even order one in... I am too thrifty and try to repair everything first.
But this is on hold as I found some Krazy Glue (Kola Loka here) and as the plate split cleanly, right in half, the glue is working!!
I have tried fixing plastic kids toys with that stuff and it NEVER works... but the ear on the wife's favoutite tea cup 'fell off' and two years of hand washing later the glue is still holding!
