Other than sous vide heaters, are there any cooking products that allow temperature-precise heating of water?
I've been thinking of pasteurizing eggs, which requires heating them to a specific range of temperatures for a continuos set of time.
I thought about finding a sort of electric kettle that has heat-preserving abilities in order to reach at simple consistent results, but looking online I can find only products aimed specifically at the Chinese market for making sorts of herbal teas with either a small set of predefined temperatures or at intervals of 5° Celsius up to 100, which might fall on a good egg-pasteurizing temperature, but that's still not as good as a higher resolution approach would have been (and I don't know if it's even accurate enough in its temperature-keeping). Also, because these products are in Chinese and their information is not clearly translated, I'm not sure they even work in the required manner.
I think in essence a sous vide can be used, but they seem rather expensive while in the product I have in mind is a simple small thermostatically-adjustable electric pot of-sorts.
Anything like this exists?

You need to hold an egg at 57C for two hours to pasteurize it. At this point, it will appear as close to raw (and yet safe) as possible. Take it to 60C and the white begins to set. So, especially for eggs, precision is essential. There is a good chart on this page to get you in the ballpark. You really need the sort of stability that will keep you within a degree or so of your target temperature. This is, of course, the beauty of sous vide. These days, you can pick an immersion circulator (what people call "sous vide") up for well under $100US. I see Amazon has one for $45US. There are other devices, like induction burners with temperature probes, or combi-ovens, but the price point is significantly higher.

What is a sous vide immersion circulator?
Breville Joule Sous Vide. Buy on Amazon. An immersion circulator is a device that you insert into a tub or pot of water. It draws water from the tub, heats it up to a precise temperature, then spits it back out, simultaneously heating and circulating the water. A good one will have single-degree precision and accuracy.How do I choose a sous vide cooker?
