I answered earlier and after reading this thread I would say. Colts are wonderful handguns but they are expensive and not made or supported anymore. Depending on how much you want to spend determines the condition of the revolver you will get.
I'd go with any of the following.
617 with 4 inch barrel
Model 17 in any dash number older then -4 or at least a P&R -4
Model 18 -3 or older
