Oh that's clever! I never even thought of checking out cooking supplies. (I ended up ordering a digital thermometer.)
As for a colander, they're inexpensive from places like Target (and Walmart, etc, I imagine). They're even cheaper if you can find an Asian Supermarket (like Ranch 99) or an Asian knick knack store (which is like your "dollar" store).
