According to my McMaster catalog (#99), they have Garolite G10 in
1/2"x12"x12" chunks for about $40 (8667K218), is this what you got?
They also have Yorolite on the next page, various grades for for $140 (G7
silicone) to $72 (G11 Glass epoxy).

You might call your local Ryerson steel distributor. They
represent/manufacture a variety of fiberglass products from the "Morrison
Molded something something" line, notably Extren (tm) pultruded fiberglass
structural components. The catalog has sheets in it. The stuff costs about
the same as aluminum for the same size and weight, i.e. a few bucks a
pound. They will have a minimum order though....
