G'day Ian, welcome to the forum.
I tend to agree with Mike, I like the pre-units, but if someone wants to give me an A65 I'll take it. Just yesterday I was offered a '68 A65T and a '69 A65L for $6000AU the pair, I'll offer him 4.
There's always A10's for sale, just do your homework, ask ? here and a picture paints a thousand words.
Good luck.
Cheers
