Basement or garage, if the external ambient temps will rise both above and below the ferm temp during a ferment (like in a garage), or even be stable at more than ~1F below ferment temp (like in a basement), a dual stage controller is beneficial since both heat and cool will be needed in both cases.
RE: short cycling- There are ways to compensate for not having built in ASD, but why bother when they will never guarantee protection, and generally degrade temp control. Especially when a cheaper ($25) dual stage controller with ASD is available.
Personally, I would return the Ranco and get the ebay controller, a fancier Love dual stage, or the Johnson digital. I don't know why the standard Rancos continue to be mentioned as a viable choice. Same goes for the inline pumps when the same exact pump in a center inlet design is superior for virtually all homebrew applications.
