I was also dissatified with the Circuit shapes as I didn't think
they looked good enough to do professional drawings so I
modified and created additional shapes.  I posted them on
the Dia List awhile back and are available from my webspace at:

http://www.hal-pc.org/~jsgil/Dia-Shapes.tar.gz

Line width was an issue and it was through trial and error
until I got it to look the way I wanted it.

I also needed to do artwork for circuit boards and have
generated some shapes for this also.
