I have a pair of campers. Leather is really nice, they're leather lined too. Like he said, the sole is glued-on. Probably worth it if you can get them for ~$150 or so. They're comfortable. Also, they run about a size big (I'm a 43 in CPs and the pair I have is a 41... though they're a bit tight.)
I've seen those Varvatos boots in about 8 places for ~$420. Check Barneys. Just be careful - sometimes Varvatos stuff looks great on the shelf and awful when you're actually wearing it.
