My thermometer came included in a cheese kit, but it was sold separately for $12.95. It's a regular dial Weiss, and so far has worked fine.
This past weekend I was checking stuff over at Sam's Club, and I found TWO of these same type thermometers (Cooper brand) for $5.24.
This comes to about $2.62 per thermometer.
This is a good bargain, I think. The readout is from 0 degrees to 220, btw.
I'm sending one of these to my sister, who I'm trying to corrupt by introducing her to cheese making.
