It looks like the one listed here has all of Paul's mods. I owned one and it's a solid integrated for the money. I did pay significantly less for mine but it only had the focus control.
I do feel at that price range there are other options out there. Are you just limiting yourself to an integrated? The reason I'm asking is that for $100.00 or so more Jim Nicholls from JWN amps could build you an excellent el34/ kt88 based amp that betters the Cayin in all areas.
If it's an integrated you're after you could probably do alot worse than the Cayin
