'02 Olds Alero Serpentine Belt Replacement - DIY or $120?

I had a 2000 Alero many years ago, and I think I had the belt replaced once for something like $20.

With things like that, sometimes the best bet is to find the part yourself online and try to find a friend who can put it on for you. I wouldn’t do that with brake pads, but belts are pretty easy, I think.
