Worse case you add a Ranco in set at an emergency shut off temp as a back up. I would get it in a heart beat even though I do not have room for it. My little incubator was around $600.00 and then I have to swap out the control systems on it since it used wafer primary and back up T-stats. I am putting 3 rancos in mine with the primary control set at 89 degrees the low back up set at 88 degrees and the over temp complete shut down of unit at 91 degrees. The incubator I am using is the same as Ballroom Pythons South uses except he uses the two wafer elements with a ranco as a back up where I am swapping to all rancos as I have no faith in wafer elements.
