CustomizeGoogle for 
pera
CustomizeGoogle is based upon the great Firefox extension CustomizeGoogle, which is also released under the GPL license.
About
CustomizeGoogle is a UserJS for Opera that enhances Google search results by adding extra information (like links to Yahoo, Ask Jeeves, MSN etc) and removing unwanted information (like ads and spam).I got the idea of porting the extension when I read a Blog post about the Top150 Firefox extensions and someone complained that there is nothing comparable of CustomizeGoogle for Opera
I have not tested every feature of CustomizeGoogle, but most of them should work.
