I realize this is a pretty old post, but was researching ZoomInfo and noticed your endorsement here. Do you still recommend their service?
Their pricing seems decent and a test batch of leads did produce some results for us, but not finding much in the community here pros/cons.
Thanks!
eGrabber is awesome. As a previous user mentioned, the interface is a bit clunky, but with proper training, you could get some really good and targeted prospect info. Consider using an intern as it's a bit manual. Also, if you're techie, try using it in conjunction with AutoHotKey to automate the scraping process. Beware of LinkedIn's recent restrictions on profile searches - not sure the impact on this product.
ZoomInfo is near the top of its class for purchased lists. NetProspex and Data.com are fine as well.
