All these new fangled temp gauges, temp controllers and instant read sure make life easier. When I first started out didn't have any of those, strictly by looks, feel, and testing. Kinda like digital never thought it would ever take the place of film ! course when I started smoking, there weren't any laptops, cell phones or internet, Wow I'm getting old ! also remember gas at $.22 to $.24 a gal. and have gas wars and would drop to $.18
