Well when you say light touring the question that comes to my mind is:
You want to put a light duty bike rack on the bike?
Because if you say YES then you put a large limit on the selection of road bikes. Seems it is cheaper to not add all of those lugs and drillings for rack mounts and such these days.
However there are actually more bikes in the $1K (US?) range that still can be fitted with bike racks.
