Thanks for the replies you two. And most definitely, I respect what kitedemon has to say as he always has some sort of evidence to support it.
I like the idea of just checking the ones on the shelves to see which are within the closest range, it's so simple but I wouldn't have thought of that.
And just to add to the test, analogue definitely ARE terrible for measuring hot side temps (was off by about 6*F, only tested one thermometer because I figured it would be inaccurate), but since ambient temps are just as important, it seems that everything has a place and a purpose then.
I was just so shocked at first to realize they did have some value to them...made me glad I threw them in a drawer rather than in the trash!
