What's the best way to choose a realtor and let the others down?

[James Dean-Howell]

I attended my local real estate meeting for the first time and connected with a few realtors there. They were vying for my business and I got a few business cards. I've already met with two other realtors and haven't yet decided which one to go with.

The issue I'm having is that the realtors at the meeting know each other and I'll probably be seeing them regularly. IF I do choose one I have a fear that the other might grow resentment.

Am I overthinking this? How do I make sure I'm being polite and respectful towards the one I turn down?
