I got 2 cars with these alternators, one since 2005. They are stock cases nothing special on the outside and cost about 150 bucks I think? I really can't remember somewhere around there.

Is it worth it? Yea I think so because they charge better at idle.

One my cars have stock wiring and AC that is why I wanted a up graded alternator for at night during the summer with the AC running. My lites stay more steady now at idle or low speeds.

No trouble out of either alternator so far, one since 2005.
