hi bomb threat, i can't seem to remember any brand names off the top of my head-it's friday night (beer night)-you know.
i would suggest you avoid those discount auto part stores, such as autozone.
i've always been partial to the carquest auto parts chain, not sure if they are in your part of the world.
those discount chains tend to sell cheesy (mickey mouse) merchandise and although they warranty them, they don't warranty your time, sweat and effort.
i live in a very hot part of the country, so i prefer to run the coolest thermostat available, currently i'm running a 180 degree in my '94 yj (2.5).
good luck to you,
