There are a few good threads on the subject. Best bet might be to do a search on it, so you don't miss any of the juicy details. /ubbthreads/images/graemlins/happy14.gif. Basically, you're getting a new and easy to use interface, a bright LED with good throw that dims, and a strobe that most of us will just use on the Mrs. but could actually be used to confuse a bad guy. Not much that you won't like.
best regards
