Huh...do you have any friends who are self described "bike nerds" that could gently steer you through the process?
If not, in answer to your initial question, the answer is yes, for example, they have a perfectly serviceable Diamondback Insight, below. BUT, the price point is high and you could likely get the same amount of bike at the LBS. www.dickssportinggoods.com/product/index.j
I would consider giving the LBS another shot at your business, see if they're responsive to some questions about helping you fit a bike properly, perhaps you just got a poor salesperson or caught them on the wrong day. That said, are there any other shops you could check with as well?
Fit is priority, if anyone just wants to shoehorn you into any ride that's in stock...that's, not ideal...
