Best to have it re-cored or replace? Anyone had any luck with stop leak products like Bar's?

Is there a good alternative / upgrade to OEM? What about this model on amazon? Not a lot of reviews but they are positive and should be plug and play:

There are a bunch of other options available on rockauto as well:

I've only heard of Denso and Hella. According to RA the TYC and Denso models are popular choices.

Replace the radiator. Bahrs leak doesn't work in my experience. It may seem like it "fixed" itself, but I wouldn't count on it. It could really let go at the worst time and leave you stranded.
