Charlie, if you consider Anova to be a gadget it's probably not for you. Don't buy a low price if you aren't prepared to learn how to use the Anova circulator competently.
First, it's not a "sous vide", that's the name of the cooking technique, - like baking. It's commonly know as a precision circulator.
You also need to go beyond looking unless you're a gadget collector.
I suggest you consider if you are ready to learn a new way of thinking about your cooking. If you are prepared to to the work to raise your cooking results to a higher level, cooking in a precise manner in order to prevent moisture loss and achieve tenderness you could only dream of, you might find the work beneficial and buy one.
If you are not prepared to think about your cooking and just blindly follow recipes, don't bother buying one.
If you peruse this Community's posts you will soon realize that a lot of users here have little to no knowledge of the technique's basics. They insist on applying conventional cooking technique thinking that doesn't apply to SV. Or, they totally depend on the Anova app's recipes to do the thinking for them and that comes loaded with challenges. Competent cooking requires knowledge and your focus on the expected outcome, - aka, thinking.
So if you are prepared to learn all you need using Anova to be able to cook meat and poultry to perfection, and almost everything else like eggs and vegetables in a very simple method, get it. You will be amazed at your delicious results.
