I do have a multi-19 as does my friend. They are awesome. Great quality, great warranty, decent weight, clean and simple. The only thing is, there's no way of locking the tools in place which can get a bit annoying but it's meant to be an emergency trail tool, not a workshop staple.
My favorite tool: Unsecure image, only https images allowed: http://www.uncrate.com/men/images/2006/05/686-toolbelt.jpg It's saved my ass more than a couple of times.
my lockring tool, because i'm really anal when it comes to cleaning my bike so when everything is being cleaned the cassette comes off and cleaned with a toothbrush
