If they're charging $100, you're paying too much. The Looney hasn't fallen that much against the dollar since the last time I checked, has it?
You can get one in the States for $75, last I checked.
At any rate, it is an awesome tool. I have the older style which lacks a few improvements, but is still my favorite multitool. I can't say if I'd spend the money on it, though, since I stole mine from my wife.
(What? She wasn't using it!)
