I just posted this on Amazon if anyone here is interested: http://www.amazon.com/gp/product/B0039LAVEM
Look under the "used" link.
It's useful for monitoring mash tems, fermentation temps, kegerator temps, or anything else you can think of. It's also a data logger so you can load the software and make some sweet charts.
4 inputs and thermocouples mean you can monitor you mash and sparge water temps at the same time on the same screen.
