refractory panels and baffles, where to buy?

I have a Scan Anderson 10 that I have been using for 3 years now. While the baffles and panels are in good shape, I'm thinking it would be a good idea to make up some replacement panels while I can still use the originals for a pattern. I have tried a lot of different search phrases but can't seem to find a a good source for Skamol or vermiculite panels. Amazon shows some fireplace liners but at a super high price. I am a trim carpenter and woodworker so the fabrication part does not worry me, just finding a source for the materials. Does anyone have a recommendation for materials and where to buy them?
Thanks!

tried local stove shops?
we carry a variety of refractory panels, in different thicknesses to cut to size for zc fireplaces
but we order vermiculite baffles (model specific) when needed
