Do you mean thermometers? I'm curious about that myself. I'm getting ready for my very first brew and it's only a gallon so my current cooking thermometer should suffice for the boil. Once I graduate to 5 gallons I expect I'm going to want something more robust.

Also, I'm interested in a device to record the temperature over time during fermentation. Devices I'm finding for sale start just under $100 and because I'm a bit of a hobbyist I'm considering building my own. I found an example of a guy who did a similar project for about $15.

Yes sorry thermometer

What is the device that keeps record?
 
Thermometer measures temperature, thermostat takes actions to maintain a constant/defined temperature. Inkbird is one of the thermostat brands that are used to regulate temperature, but there are many more. There are a lot of threads about both thermometers and thermostats (some of which are able to record values) if you perfoem a forum search.

I’m a dumb ass and meant thermometer
 
The Thermapen Mk4 gets high marks, but also sells for around $100. I recently picked up a <$15 Inkbird brand thermometer. It was accurate out of the box and has been accurate for the handful of brews I have used it for (https://smile.amazon.com/Inkbird-Digital-Thermometer-Barbecue-CandyThermometer/dp/B078SQD4B3).

I have been having accuracy issues with my 20 year old dial thermometer lately, but I do like that it has a long stem and can clip to the side of my kettle.
 
I'm a big fan of the Thermapen for speed of reading, and it's one of the first brewing upgrade gadgets I recommend to new brewers. Having said that I'd really suggest going for the Mk4/Professional model because I'm not sure the Mk3/Classic stands up well to brewing.

After using my Mk3 for about 18 months I started having problems with getting it to turn on when opening the probe. After opening it up I found that the contacts on the switch inside the hinge had corroded due to some liquid ingress. I've cleaned it up and fixed the problem, but it suggests to me that the Mk3/Classic model is not ideally suited to brewing where it's going to come in contact with liquid at some point.

The Mk4/Pro version is better sealed up (supposedly waterproof, although I've not tested that) and I've been using that for over 2 years without issue.
 
I have a Thermoworks RT600C. Bought it a couple years ago based on a recommendation from one of the well known members of this site. It's quick, although not as quick as a Thermapen. They say 5 seconds, and I'll back that up. It's accurate and affordable. I paid about $25 directly from thermoworks' website.

I bought my second Inkbird controller at about the same time, so I tested everything. I took both Inkbird probes and the thermometer probe and wrapped them all together. All three read the same, to a tenth of a degree. I'm not guaranteeing they're dead nuts, but they can't coincidentally be off EXACTLY the same, right?

I would definitely buy it again.
