That Fairfield Metro area is about to explode with apartments. And obviously great transit access. But I don't think it's particularly cheap, unless you're comparing to places like Manhattan or Greenwich.

Fairfield, CT is pretty expensive, especially near the coast. It's just cheaper than the really posh Fairfield County towns closer to Manhattan (Greenwich, Westport, Darien, New Canaan).

Black Rock is definitely cheaper, bc it's in Bridgeport. It's a pretty nice area, and you're right next to Fairfield Metro. If you don't need public schools, it's probably a good option.
