I'm using a BellO ATC-2101 rack, (as shown here ) and don't like it very much. Even though it is rock solid, the slotted beam in the back to tuck the wires into can not handle all of the input/outputs that I have, so I end up having wires pokin' out all over the place. YEUCH!
it is just a rack man... i would think the number 1 concern would be with if it fits the styling of your room and can support your load. many can accomodate that task...
