Radiator Recommendations for a 1994 Cobra?

Just discovered that my SVE radiator has sprung a leak in the fins near the driver's side. It only comes up when the temperature is hot, but with enough bumper-to-bumper traffic it's enough to drain the overflow tank every few days. It lasted close to 4 years, not bad considering the price. But the SVE never felt like it cooled as well as the Fluidyne I had before it. I've had 3 SN95's, and they all would stay cool over 40mph but eventually get hot and turn on the fan in stop-and-go traffic. But the SVE felt like it stayed hotter longer than my old Fluidyne. Granted, I haven't measured this and it's just my opinion. I like having extra cooling capacity, so an upgrade would be nice. But I don't want to spend a lot of money on a Fluidyne or an AFCO and only have them last as long as the SVE.

Anyone have experience with Fludyne and/or AFCO radiators? How long do they last? I'm hoping for longer then 4 years. Or is there another radiator you might recommend?
