My wife and I each have an Aurora and we love them!
Mine is a 2001, I got it new on e-bay, unbuilt, in the box for $350. I switched the Sora brifters to bar end shifters and aero levers right away, upgraded to a LX rear derailleur. Other than tires, chains, a cassette, a middle ring, and finally the rear hub, it's given me at least 10K miles of trouble free commuting and touring service.
My wife's is a 2003, another e-bay find, new from a shop in Portland, OR for $375. It came with Sora, but I hear the new ones are set up with Tiagra (9spd). After around 5K miles, I noticed some hairline cracks starting around the spoke holes in her Ritchey rims, and I flat wore out my rear hub, so I just built a pair of new rear wheels for us both using Dyads, XT hubs, and Wheelsmith spokes.
The frame is tig-welded Reynolds 520 steel, lots of lugs for racks and fenders, and worthy of upgrading components when they wear out. We have done self supported, week long tours in OR and WA with front and rear panniers and are planning an east to west Trans-Am for 2008. I don't think you could go wrong with this bike, we have been very pleased and would do it all over again. Jamis delivers a lot of bike for the money.
