Is it reasonable to have multiple agents find deals at the same time?

[Josiah Halverson]

Is it reasonable to have multiple agents find deals at the same time? My thoughts are that a few realtors looking at the same time would have a better chance finding good deals. It seems fair to me that the first agent to show me the deal should be the one that gets the commissions. But I wasn't sure if there is often a contract for the buyer to exclusively use one particular agent.
