Be honest, ask for catalogs for new bike brands, ask to see the used bikes.
It took me 2 or 3 weeks of regular visits to my LBS to decide (and purchase) my new $400 bike. I still go there every week or so for different little things and big things, and have sent a few people there. It didn't hurt them to spend that much time for my cheap purchase, because I'm now a loyal customer.
I'm happy because they know me and my bike. They're happy because if I want something I buy it from them or ask them to order it for me. They will meet advertised prices from other places if someone else has it cheaper. I'm happy, they're happy, and my bike gets ridden.

Find the LBS who meshes with you. You won't regret it, and neither will they. Just be honest during your search.
