The 7search tool is only usefull for 7search, google doesn't accept gambling ads so these terms are useless if you're looking for good adword keywords.
Also, if you check other terms at 7search using their pricing tool you'll see they're relativly low. I guess a large chunk of gambling PPC rev is going to 7search instead of google/overture

This does give us gambling guys a way to have 'adwords' with gambling by using 7search's adwords clone, AccessoryAds.com
