Thanks.. I have actually found one near me (I've been seeing cyclists pass right by my house for ages on the weekend.. always wondered what they were up to, and now I know!) and hopefully that would be a good lead to a used road bike if I do end up buying used.
I did try a couple of road bikes before I bought my 7.2fx and none of them felt right - they all felt "weird" for lack of a better term, but I do find myself wondering now if some of that wasn't just inexperience.. I'm not exactly unhappy with my bike, it just has a few things that I think could be tweaked - much like going through a few saddles to find the one that was "it" for me, I don't think it's unreasonable to try different handlebars too.
