I bought a 50cm 2008 Jamis Aurora and love that it's geometry is so similar to my Soma Double Cross. It even has the rear brake cable routed along the side of the top tube for limited cyclocross and occasional hike a bike action. Most of the my components were immediately swapped out for slightly better but slightly used Ultegra and LX I had laying around though.

I have three comments:

Budget for a second well built 32-spoke road wheelset and run the 700x28c Zaffiro Tires on them. They aren't quite enough for rail trails and crushed limestone stuff. Running wider tires on a 30-40 milers also makes them much tougher than they have to be.

Put some wider tires on the OEM wheels ans use them for the rail trails and such. Make sure a good wheel man goes over them for proper tension and stress relieving. You may have to let a little air out to get tires with big, 37mm or larger casings between the rear brakes.

I use mine in the rain a lot and the stock brakes suck in the wet stuff. Get some Kool Stop Salmon Thinline pads on there. They will also help with the rear brake clearance.
