I would never spend $1200 on a new Trek 520. The shops will dicker. Flash the cash if you must have a new one. My 520 is a '98 that I bought on CL for $550 in mint condition. They're out there. This is a suberb all pupose bike. Geared a little high for loaded touring but I think most people are like me and just ride for everyday use. So, the gearing is actually very good. It makes a respectably fast road bike.
My other bike is a Trek 830 mtb. A md-low end bike in '88 but nonetheless a very good all purpose machine. I've changed the tires, saddle and bars for long distance work. All the eyelets and hardpoints of the 520. More, in fact (double eyelets in front - single on the 520). It has very long geometry and would make a very good tour bike.
Both bikes are comfortable for day trips out to a century. I can't say which one I prefer, honestly!
