I bought a radiometer from Science City. It cost $14 plus taxes.
Cool store, located in the Holt Renfrew Centre, subway level , near Yonge & Bloor. They have some astronomy items. They also appear to sell telescopes.
It's funny how the function of this simple device is subject to heated (sorry about that) debate...
