I was at Fry's Market Place at Baseline and McClintock this evening and looked in the flashlight section and viola, Coleman brand battery (4AA) blacklights for $5.99.  Although I already have a professional short wave light I use for prospecting (and a little geocaching) I picked up one of these long wave units.  It works just fine.  As an added bonus, it comes with a regular white fluorescent light bulb as well and some glow in the dark stickers (coming soon to a cache near you).  Enjoy!
