I see what your talking about now...that item (on Mcmater) is actually an linen based phenolic material...which is similar in mechanical strengths to the G10, but is not the same material. The G10-FR4 is an epoxy impregnated fiberglass material. The "Garolite LE" is a continuous cotton woven cloth impregnated with a Phenolic resin binder and is always much cheaper, but doesn't maintain the same chemical resistance and temperature ratings as the G10/FR4 material. The company I mentioned above doesn't sell sheets or blocks of the Garolite LE, but they appear to machine it : [link=http://www.jjorly.com/phenolic_machining_fabrication.htm]http://www.jjorly.com/phenolic_machining_fabrication.htm[/link]

Now I understand why it was so cheap....thanks for the clarification.[8D]
