Biofeedback devices for PC?

[dmcg]

Sorry if wrong section not sure where it goes but I plan to do a project using biofeedback devices (usb connection preferred )to see how people respond to certain things in a game and just wondering if anyone knows where I could get a cheapish device that could be programmed with game engine software like XNA

thanks

Probably be better asking this in the programming subforum.
