Comparison of Exclusive Listing Services

Looking to join REBNY and puzzled by the broad range of options as to exclusive listing services (and lack of guidance as to costs and quality). I realize REBNY needs to remain independent but also would prefer to avoid having to call up and listen to sales pitches from all these services. I would appreciate ANY opinions, insights, data, etc. on relative quality and costs of the following: Real Plus On-line Residential (OLR) Apply Media Inc.’s RealtyMX BrokersNYC Solid Earth If you're comfortable and it's easier to have an "offline" discussion please share your contact details. Thanks all!
