Fw: recommendations for a response box with a knob

It may or may not be considered cheap depending on how many of them you need to purchase, but check out the Griffin Powermate Knob:
I've used one of these as a victim in the experimenter/subject relationship.  It has quite a nice feel to it.

Subject: recommendations for a response box with a knob

Hi all,

I want to do a lateralization study where the users indicate the location of a stimulus by turning a knob (a low-rent version of a pointer).  Does anyone know of such devices with a USB port that are reasonably priced (i.e. cheap?).  Thanks for all suggestions.
