(OP)
I need to prototype something and I can't find 8" barstock of delrin (polyoxymeth..). Is there something else anyone can recommend?

Depending what you are trying to accomplish with the prototype you might look a machinable waxes and other material offered by the likes of Freeman Supply, Machinable Wax, and Calwax.
Freeman Supply has a good cross section of pattern and prototype materials.

Depending on the requirements you have not disclosed, cast nylon might also be an alternative, especially if it is filled with some fibre.

Are you sure?
According to "Engineering materials" 8th edition Budinski, page 152:
"The homopolymer has higher strength than copolymers, but the copolymers are more stable at elevated temperatures; maximum continuous use temperatures are as high as 220F (104C), compared with 195F (90C) for the homopolymer."
Or am I misunderstanding you?
