What is the financial benefit of a Buyer Broker?

[Joe Luciano]

I am trying to figure out what a "Buyer Broker" is. Are they like a real estate agent with less perks? The main reason I'm asking is because it sounds like you can share the commission on the purchase of a home and put it towards the closing costs for example. How do I find a buyer broker? If I find a home I'd like to purchase, can I just call up a "buyer broker" I know and will he/she expect to split the commission? What are peoples experience with buyer brokers? I just want to make sure I am purchasing in a smart way. Thank you in advance.
