I was in Lee Valley Hardware a few weeks ago and found a couple of interesting things.

They have authentic Kolsch glasses for cheap. $13 something for twelve. It's the proper 20 cl stange. Since it's the weather for a nice Kolsch I imagine alot of people have one kicking around. Some how it tastes better out of a real stange. Still I don't have a Kobe bringing me a new one every few minutes so it is a PITA to keep filling up.

Second they have real nice refractometers that read in Brix and are perfect for brewing.
