Help with joining a real estate trade association in NY?

[Joseph Delossantos]

Hey, everyone! I have a question, should I join REBNY, or RealtyMX? I was told RealtyMX was like $50 to $100 a month depending on what you select, and REBNY charges $300 a year . Heard that REBNY is popular. NYC RE Agents/Brokers, which trade association should I pick? Are there any trade associations of similar capacity besides REBNY and RealtyMX? I am concerned about leveraging my costs to start up, so many choices but want to make the right one.

Thank You!!
