Thanks everyone. I guess I'm going to have to drive a good ways to find another bike shop. I'm in the middle of nowhere Texas and the LBS is the ONLY LBS around. And the one 30 minutes away is the same company!

The first road bike I tried was a Giant OCR CW, carbon. I thought maybe the lightness of it was part of why I couldn't feel steady, being so used to my heavy Navigator. Most recently I've tried the Surly Long Haul Trucker. I thought maybe by beeing a bit heavier, I might feel more stable. I really want to like that bike. I have no plans of racing, just being comfortable for long rides.

I just recently moved (there was a great LBS where I came from, but they'd only opened a month before I left). And all my stuff is in another state, but I think once I get my indoor trainer (I bought it so I could ride while my arm was broken , I might try again on the LHT. I think that then I might be able to tell more if it's the fit or my own unsteadiness. . . you know, if the bike is being held up on its own.

I'm not sure why I chose cycling. I have terrible balance and hand-eye coordination!
