My first "nice" bike was a 2008 7.2 FX. We've had many happy rides, some long (50-60mi) together. I decided to buy a road bike this summer, but my Trek and I are spending just as much (if not more!) time together as I've made it into my daily commuter and around-town bike.
The FX's are great bikes--there are a few of us fans around here. I can't give advice on the pricing on a used one, I suppose it will all depend on the condition it's in, and more experienced folks could probably give you tips on things to watch out for.
Regarding your and DH's decision between road bikes and hybrids... some folks would say go straight for a road bike, but I'm so very glad that I took that step in between (I had been riding an old, clunky, ill-fitting mountain bike purchased at Sportmart) before taking the plunge on a road bike.
Good luck!
