I was in much the same position. I spent the summer riding a Trek 7300 and after completing a few centuries on it I found myself looking for a road bike.
I opted for the Salsa Casseroll. It's croMoly and is somewhat lighter than the LHT and other purpose built touring bikes like the Trek 520. I like the fact that it came built with full 105 group, including STI shifters instead of bar ends, 10 speed cassette, 700 x 32 (mine is a 55 cm frame. Smaller frames have 650's, I think) and fenders. Salsa has been making rims and skewers for a while, and the Casseroll is built with Salsa rims laced to Tiagra hubs with DT Swiss spokes.
Another big plus is that Salsa ships the bike with the steerer tube uncut. This means that the LBS where you order it can pretty much fit the riding position to your specific need. The mechanic/fitter where I bought mine suggested that after a while I could have him change the position by moving some of the spacers from under the stem to on top of it. Very versatile.
I added a small handle bar bag and a couple of fenix l2d lcd lights. I'm scheduled to take it on its maiden metric century
Sorry for the shameless plug, but I just LOVE this bike. One of the coolest things is that you are not likely to see too many of them on your next group ride. The exclusivity factor is worth something, too
