Here is another source of first surface mirrors for artificial horizons:
http://firstsurfacemirror.com/
There is a choice of 1/8" thick or 1/4" thick and any dimentsions you want. A 6"x6" was $20.00. Service was prompt, shipping the same afternoon I placed the order. I chose th 1/4" thickness because the thinner mirror I had acually flexed a bit with the weight of the levels. If you have not tired first surface mirrors, theyallow very low angle sights without errors caused by host images.
