SR is a chinese alternator but then... so are all the other reman'd ones you can buy at the box stores. I'd get it and run it and it will likely be fine. A 3G alternator is 130... you know I never actually bothered to find out if this changes at any point in the 96-04 run.
Alternator is STUPID easy to change as well on these cars. On some cars you have to pull the motor or drop the trans.... yeesh...

Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
