Is it seriously just any light dimmer? Or is it specifically something specialized? Do I go to Radio Shack and get the unit for $5 or can I just go to HD/Revy/etc. and get one there? (I guess I can go to Radio Shack, it's just that Revy is right across the street from where I work, and HD is about 1 minute away from my home ... so those are an order of magnitude more convenient than anything else for me...)
