When should you listen to the store clerk and follow his recommendations against your own inclination and intuition? Never. If you feel a camera is easiest to use, is solidly made and we have it listed, you're on safe ground. If you are hung up between two cameras, then perhaps you can listen to what suggestions the salesman may have. But remember -- he's getting a commission on the sales and the commission varies from camera to camera and you don't know just how it varies, so... listen with a grain of salt in the ear.
