i actually think these things are priced pretty fairly given their track record and history of wonderful customer service. they have everything you want from a company you want to do business with to have. their products were originally for labs grade and came in only gray and then they started making white as well and then went on to the colors for restaurant use to be able to differentiate between thermo. for beef vs. pork. vs veggies, etc....
it's just rock solid and when you can pick them up fairly frequently for under $70 and always less than a bill, and you couple that with how often you can use it and for the different number of uses and all of a sudden, $70 starts looking pretty damn good.
