The alternator on ebay that is linked above isn't a genuine Denso unit!
How do I know? I bought one as a spare this week they are a JAS copy.
I spoke at length to the guy in Adelaide and he swore by them, I found it to be a good quality unit when I got it.
That said the one I got did have a problem but they quickly replaced it
They do have a good quality feel to them when you take them out of the box
