Depends on what you are looking for. I have a redsea e170 max (rimless) and it was cool until the lights really started bothering me while I was watching TV. Even with light shades I ended up building a custom top for it and I love the way it looks and it cost me all but 50 bucks to convert. Personally I love the look of a top on a tank, and will keep that in mind for my next build...here are some pics of the early beginnings.
