Possibly ebay, or a used tool dealer, or if you're lucky a certain
'homeworkshop' site. They're fairly pricey new.
The metric collets generally have a groove machined on the edge of one
of the 'ears' for identification.

J&L sell them, their own brand are reasonably priced & aren't bad,
the ones I've bought (actually mainly slot drills) have been 'made in
England'. I've also picked up little packs of Dormer endmills at one
of the shows for what I thought was a fair price.

ER are very useful and adaptable, but they aren't as secure for
holding milling cutters. Lots of people say they've never had any
trouble but I've had cutters slipping and pulling down. Autolock won't
do that. ER should be fine if you aren't into heavy cuts.
