We have a Little Giant 9200 . . . and I don't like it at all. From what I've read here, the thermostat is pretty 'hit or miss' as far as it's ability to hold a steady temp. Apparently we got one of the "misses'. Further, I hate trying to fill the humidity trays with water, particularly if you have the egg turner. For filling the trays, I use a syringe with a piece of aquarium tube stock on it to fill the trays, but it's a poorly engineered design.
One thing that helps with the "tweaky" thermostat adjustment is to simply put a large knob on it. It's MUCH easier to 'microadjust' with a knob. That stem is simply too tiny to move it in hair-like increments necessary to get reasonable temp adjustments. It's like if your heart beats while you're adjusting the 'twig-like adjustment stem, you bump it up or down three degrees . . .it's quite frustrating if you don't put a knob on it. I save knobs off old electronic gear, so I had one the right size, but Radio Shack probably has something that'll fit.
I'm building my own, that way I know it will do the job, and be easy to use . . . If I can Just get the RANCO controller to function right. It won't shut off. I've checked and double checked the wiring diagram, but it just leaves the element on constantly, even tough I can hear it clicking at the proper temperature.
Just my thoughts, some folks love their 9200's . . . guess they got one of the "hits" . . .but even in a best case scenario, it has some shortcomings that simply redesigning the mold they blow the polystyrene in could easily solve . . .and dang! Miller Mfg . . .how about including a knob, and charging an extra 2 bucks or something!
