I have a 2011 Trek FX 7.3 that is a hybrid with flat handlebars. Their FX is their most popular platform and it can be used as a commuter bike, fitness bike, leisure bike, etc. I put on fenders, a kickstand and a rear rack, along with lights, a loud bell and a computer. It has 700 x 32 tires, so thin but not as thin as a formal road bike. I am in a bent over position, but not nearly as much as I would be on a true road bike. It cost around $750 without all the accessories. If you want disc brakes you can get those for $100 more.
Good luck and let us know what you decide.
Have you thought about 2010 close out models?
