Which one had the high gearing?

What did you like or dislike about your Kona Sutra? Why aren't you looking for another?

Are you actually going off road? Gravel?

Of the cyclocross bikes, the Specialized Tricross would also be similar.

There are a few CF Cyclocross bikes, but they tend to be expensive. Nashbar does sell a CF Cyclocross frame for $700. What can be recovered from your old bike? For $500 to $1000 more, you could build up a very nice bike.
Nashbar Carbon Cyclocross Frame and Fork

Or, this one has rack mounts (but canti or V brakes).
Pedal Force super-light carbon bicycle

This one has discs, and at least lower rack (fender?) mounts.

There are a few Titanium Cross frames for around $1000.... Might be worth considering building up. There is another thread about hunting for a good Titanium Cyclocross frame.

Anyway, there are a lot of options.
