Hey there Mazda lovers, like myself

Anyways, long story short, the other day my 97 Miata overheated. This brought my attention to the radiator, which was surely the cause of the problem. The part showed signs of coolant leakage and a good majority of the fins were damaged as well.

I've decided to buy a radiator online, as this will be more convenient for me, but I'm just not sure which companies I can trust. Have you guys ever dealt with either

or

??
Those are the two that I've narrowed it down to, but I don't want to take the next step of purchasing before I'm sure of what I'm doing. Thanks in advance.
