$80 isn't bad. I've seen many quotes much higher. As far as non-Nissan brand ATF goes, you will be okay as long as you stick to the equivalent called for in your owners manual...probably dexron III for an '03. Amsoil is a fine dexron III equivalent.

Watch out for the newer cars when selecting ATF. Nissan has departed from the old practice of prescribing a fluid that is compatible with Dex, Mercon, etc. Now, they require the use of one specific Nissan fluid, and warn of certain trans damage if you use anything else. As an example, the current Max requires the use of "Nissan Matic-K" in the 5-speed autos (not sure about the 4-speeds). My G35 (5-spd auto) manual basically says to use "Nissan Matic-J" or you will damage the trans. There are no equivalent alternative fluids that are allowed. Gee, not surprisingly, the Nissan ATFs are more expensive than the general OTC fluids. Go figure. . .
