This is all really good information. Can you please give us some more information about the use of a blacklight (or point us to a good thread that has more of that information). I just spent 2 minutes on ebay and see some really inexpensive blacklights ($7 is cheap in mind - especially when people I know spend that much on a cup of coffee). If I have a blacklight - what do I look for? What is the best way to use it?
