Bigdevil
I don't know if bigdevil is any good but I'm still testing goodbomb - and the first completely blind, unsolicited, don't know wehre it cam from use is on a forum page saying bigdevil is good. At the time of writing this bigdevil is good is no-where in the rankings if you search for bigdevil - so I thought i'd try it.
It's a prize winning search engine - pretty much like blingo.com - and I think that's pretty good so i can't fault bigdevil - it gives me google and the fun of potentially winning something - so thumbs up
