What companies are you using for Residential Seller Leads?

[Erich Morgan Weiss]

Hi Everyone! 
I have been a fan of BiggerPockets for years ,lots of great info and real feedback. Finally joined and this is my first post. I am a 25 year Real Estate agent in SoCal (mostly residential however venturing more into commercial; and getting back into investing in other states as well, which will be my next post) I have tried quite a few lead services and while some may do better in other areas of the country , most seem to a flop in this area, of those tried HouseJet, Reaology, USHud and Realty Bargains( Realty Bargains was the best however they kept sending me mostly investors who's matrix would not pencil in the areas I serve) I am doing my best to figure out social marketing, my views/impressions are good however that has not turned into transactions as of yet; So I am on the hunt for a 3rd party lead co with quality Seller leads. I am currently using FUB/Ylopo and zBuyer, working with a few Ylopo social/PPC leads right now but they are going to take Alot of work to convert, zBuyer for SoCal are 99% seniors that are just curious about their home value, so while there's been conversions they are far and few between. Has anyone tried Brokerspot, Connektor, Grizzly Leads, Deluxer, RevIUp or suggest something that works/has a reasonable spend w good ROI? I'll add while not a big fan I checked into Zillow and they are suggesting a $90k annual spend for 5 possible leads per month in areas 1-2 hrs drive from my office and mostly buyers, that makes no sense for my current goals. Thanks in advance for any insight and responses.
