Electric choke on Slant Six

Does anyone out there run a slant six with electric choke? There's someone on ebay who sells them for $50, and I'm curious as to how much it really helps reduce stalling and rough idle.
It might be better to check your carb and intake manifold gaskets for fuel/air/vacuum leaks instead of the electric choke. Like Rusty said once your engine is warmed up the choke won't help.
