I also have several Italian made keyless chucks, one I got from a firm not far from where I live (I live in Italy and this firm makes chucks among other things,including lathes, they're called COMEV)it's 0-10mm (yes 0!, it will hold a 0.2mm drill bit if you're patient to set it properly!) it's superbly made, there are a lot of small firms struggling to keep up with imported stuff here, and Italians are damn good engineers, they make beautiful machines, some stuff comparable (CNC included) to your Hitachis etc.
One thing I might add though, is the fact that there is still no law that says "MADE IN ITALY" can only be stamped on things "entirely", or even partly, made in Italy, so as a consequence, there's a lot of stuff (mostly clothing, Prada. Gucci etc.)that can be farmed out to Bulgaria or somewhere (China included BTW) which comes back with "Italian made" written on it!, I'll say no more as I'd like to continue reading and writing posts here!
