Default Difference between Johnson A419 models?

Is there any difference in models between the grey Johnson A419 controller and the blue one?

Midwest Supplies (grey) - $75.95
http://www.midwestsupplies.com/johnson-digital-temperature-controller.html

Northern Brewer (blue) - $79.99
http://www.northernbrewer.com/brewing/johnson-controls-a419-digital-temp-controller.html

I'm looking for wired since I have none of the tool, or experience to do the wiring, so these are the best prices I've found --- any other suggestions for better price?

The temp differential adjustment is different, as is the probe lead length. The NB description says the adjustment is 1 - 3 degrees while the MW is 1 - 30.

the differential is configurable between 1 and 30. NB must have forgot the zero.

So, there's no real difference -- aside from the possible difference in probe length?

yeah, no difference aside from possible probe length. wiring is done after the factory, so that might be a little different too.

fyi, midwest says "out of stock"....
