[vcf-midatlantic] Known-good IBM joystick?

I'm having issues with the VCF supply of Kraft joysticks, and there is no time to fix them before HOPE. Does anyone have a tested and fully-working / known-good IBM (or other non-Kraft) joystick which I could borrow? I need it by Friday in order to test it at the museum this weekend. Dean said he may have one, but in case he doesn't.... My backup plan is to program for keyboard control instead of joystick control, but that's not nearly as much fun.
