I didn't know these existed until I joined this forum! 
I picked up a Mastercraft one on the way home...even though it was 50% off it was still a tad expensive...so I will assume it's decent quality.
How accurate are they? It doesn't quite mesh with the digital thermometer. ..and when I went to test it out on a parrot it measured her as being 65°F. I'm pretty sure she's significantly warmer than that.
