Cheapest for me was a new Valeo unit from Rockauto. Cheaper than Turner too.
Pros: Cheapest unit
Cons: Cheaper than Turner
+1 for Valeo. This job wasn\u2019t fun.
Pros: Good quality
Cons: Difficult job
If you\u2019re looking for cheap, go with the new WAI alternator. With the new alternators, you don\u2019t have to worry about sending back a core either.
Pros: cheap, no core return

I got toyota denso brand from rockauto site for $255 with shipping included
Pros: good price
Replaced mine with a denso from rockauto. Unfortunately, the battery light stays on even though the voltage readings are good and have been driving like this for almost a year now.
Pros: good voltage readings
Cons: battery light stays on
Autozone will give lifetime warranty on certain (duralast gold maybe?) alternators. I got the replacement very wet (dumb), and it died while I was driving.
Pros: lifetime warranty
Cons: died while driving
Ohh boy, we had a brand new range Rover that needed an entire transmission because... That's where the alternator is. It's not separate. It's only serviced with the transmission.
