My thoughts
It's between the KHS and the Jamis. The Kona shouldn't even be considered, as the fork is flat-out substandard. Check Marzocchi's web site for the Fondo series forks and their intended usage. They're not even fit for use as a standard XC fork. Kona has used this fork on a few models this year and I can't imagine what the folks at Kona were smoking when they chose to spec their bikes with this fork.
As for the KHS and Jamis, I'd say it's a tossup between the two depending on what you're looking for. If you like Fox air suspension, then the Jamis wins. If you like Marzocchi, then the KHS is the way to go. The cranks on the Jamis are better. I can't speak with any degree of authority on either bike's brakes, as I'm unfamiliar with Hayes hyrdos. On the surface, my money would be on the Jamis, but I think either bike would do. It's a personal preference thing.
