| Tom,
I've purchased G10 from http://www.mcmaster.com/ in the past. They stock different colors and thicknesses. A 12" x 12" sheet of .062" black G-10/F4 Garolite is $5.80. Just type G10 in the search. 12" x 12" is the smallest they sell I believe.
Nathan,
Pulled from McMaster's site - G-10 is a "continuous-woven glass fabric laminated with an epoxy resin".
McMaster's site also has a really nice PDF spec file on G-10. Here's a section of it:
Colored Sheets (85345K):

Tensile Strength: 50,000 psi
Impact Strength: 12 ft.-lbs./in.
Dielectric Strength: 550 V/mil
Durometer: Rockwell M: 111
Coefficient of Thermal Expansion: 0.9×10 -5 in./in./°F
Weather Resistance: Material is not weather resistant.
Processing: Machinability: Can be easily machined, sawed, drilled, and tapped.
Welding: Not recommended.
Scratch Resistance: Material has excellent scratch resistance.
Chemical Resistance: Unaffected by most organic solvents, resistant to dilute solutions of most acids, and not recommended for use in alkaline solutions.
