This site has some cool GSR related products:
http://www.mindgrowth.com/store/

You could just make your own metal plates and hook them into the unit.
The GSR units from Mindgrowth output an audio signal which you could patch
through to something like this:

There are also instructions to make one from scratch:

Cheers,
