Good teddy bear hamster cages?

I need a good cage thats not to expensive, like 30-40$ from petco. I chose this cage but people say its to small http://www.petco.com/product/106173/PETCO-Playhouse-2-Level-Small-Animal-Habitat.aspx?CoreCat=OnSiteSearch .... so if you have any other ood cage suggestions, tell me...need links to.
