Yup. The other one to look at is the Johnson Controls A419. A little pricier, but has a few different features. Both are top notch quality industrial controllers. I run the A419 on my tank and can't believe I waited so long to get one. The more $$ you start getting in your tank, the more you start getting concerned about how quick it could go away just because of a stinkin' stuck thermostat.
But to answer your question... I think some of the Ebo Jaegers have an adjustable dial so you can make your thermostat reading match real life. I think. But that still doesn't mean it's not going to drift over time. Better to just set your heater based upon a well-placed (like not right next to the heater!) digital temp probe. (Even with a controller, I still have 4 temperature probes in various parts of my tank. One is for the controller itself, one is one of those temp alarm units, and the other two are those little Coralife digital units. Obsessive? Perhaps...
