Aftermarket radiator

My radiator has a little coolant stain. Want to replace it before it becomes more than a stain.
I see people putting mishimoto all aluminum radiators in their first gen tundras, but I haven't seen one installed in a first gen sequoia.
Anybody seen this done in the Sequoia or know of a better than factory radiator?
Edit: I have a 2007 Sequoia Limited if that makes a difference.
