As much as I love Microcenter, even there I've had a salesman give me uninformed advice, throw his bar code sticker on the thing he told me to get, and walk away.
So don't talk to that guy again. The others should be fine, unless your local store happens to have a lousy GM.
Initially I dealt with this concern by benchmarking the advice I got on a topic I do know a lot about. I haven't worried about that in a while; at least in the Towson store, the quality of advice and discussion has been such that the next time they steer me wrong will be the first.
