Which broker / agent / office did you use?

I'm inspired. Anyone can answer, but particularly curious about those of you who have bought/are looking in Queens, Brooklyn, Bronx. For those of you who have bought or are currently looking: 1. Are you using a buyer's broker? Are you exclusive or using multiple brokers? 2. Which broker company is it? (If you feel comfortable disclosing) If more than one, list all. 3. How did you find them? 4. Do you look for listings on your own? If so, what sources? 5. What borough and neighborhood are you buying (or recently bought) in? 6. Overall comments and observations you have.
