For that money and ease of use and maintenance I love the EHEIM Liberty
HOB filter. They have paddles inside for the carbon and for the sponge to grow the biological filter on. I love mine and they are really easy to maintain. For a canister but more expensive, the Marineland C Class cannot be beat. I love them for all reasons imaginable. They do a wonderful job, are easy to set up, come with easy instructions including a DVD that shows everything, have wonderful customer service and are very easy to prime and maintain. (but they do not fall in the price range you mentioned)
