I don't know when you started collecting gear, but it used to be very difficult and expensive to find two-piece pro stock pants in decent shape in any brand. If you could get your hands on a pair that were new or lightly used, the prices were $100 higher than they are now. Good luck finding smalls and mediums from a team sale. If you could, whoever was selling them made out like a bandit on their resale. Then that Hockeymonkey shipment hit the internet, every pair of pants was brand new, and there were a lot of them in every size, for every team. It changed the marketplace, and that's why there's so many Reebok and CCM 520s and 7000s around in sizes that you'd never find at a team sale - there's not too many NHL players wearing little pants.
You started off saying "CCM and Reebok aren't really rare though the way Bauer seems to be these days"
I'm telling you why that is.
