Header opinions

I have a 1992 4.0l and my engine just went out, I'm getting ready to drop a new one in it, however my exhaust manifold is cracked as well. Luckily I was beginning to go through it front to back and redo the whole thing anyways. So while it's all out I was going to replace the manifold with a header but was looking for some opinions, I want something good but I also don't want to spend an outrageous amount since I am putting a new motor in at the same time.

Borla , Banks , and JBA are always great options

I bought a APN (banks clone ) for my XJ (uses same header As a 4.0 wrangler ). It cracked after 2 years now I am saving my pennies for a JBA to replace it.

Mine came with a Doug Thorley header already installed. It looks like its been on there a long time. Good looking stout unit with thick flanges. No cracks or leaks. Bolts up to the factory head pipe.
