places to buy cut glass for cheap in Bay Area

[pandamonium]

I'm looking to get a glass cover for a tank as a replacement. Does anyone know of a place in the Bay Area that does this for cheap? I would like the edges to be sanded as well.

Was also thinking about making my own rimless tanks as well. Does anyone know of a good place to get rimless tanks/get glass to make rimless tanks?

Thanks so much
