I monkeyed around with a bunch of other menu extensions, none of which were simple, and still required too much mickey-mousing around with code to fix for IE6, etc. I wasted 3 days with those things.
This extension was fully customizable from it's component backend. It worked with every browser I tested it on immediately. Awesome! And it's FREE!
Luckily, my client only needed a couple of drop downs for this site, but if I ever need a lot, I know I can always pony up for the Pro version. To me, it's worth money to save time...which IS money...
Anyway, thanks, Sean!
