See my comments below before completely ruling out KONA. They now have gone to the 520 size (I think). There may be more available there. Just be careful that at the 507 size it seems there is nothing much available under 2".

Also, consider whether when you are considering bikes if it is to be used for longer road rides whether you really want 2" wide tires on there -- even if they can be squeezed in.

I'd look a ISLA and Redline for versatile alternatives.
