Almost, way too much. For your first thermometer i think your examples are more than you need.
The British made Thermapen is considered to be the professional culinary standard. Personally, i think they are far too expensive for what most folks need.
Most retailers that sell kitchenware and housewares have inexpensive dependable instant-read digital probe thermometers. A slender one piece hand held instrument is all you require. Look for a thin tip. If you are trying to choose between several, simultaneously pinch the extreme tips of the probes and choose the fastest responding one.
The Ikea “FANTAST” thermometer is an inexpensive versatile combination thermometer and timer. Its long cable allows you to monitor oven or BBQ cooking in progress as well as checking SV endpoint internal temperatures. This is not a recommendation, just an example at a very reasonable price. I have two like it that i use for smoking food and a one-piece digital probe thermometer which is used most often.
