Quick update for me. I got the thermometer from the original post and while making a starter last night, I put the probe in the boiling water (only water at that point) and after about a minute or so, it stayed between 211.6 and 212.6. I think this should work out well. I put the thermometer I normally use in since I thought about it, and it read around 214. I'll have to try these in ice water soon.
As mentioned in one of the amazon reviews the Taylor thermometer from the first post does not have an on/off switch.
Thanks for the help, I need it.
