I have been on the search for a practical solution to organize and display my large cd collection.  I have bought several urban/industrial style racks in the past, but this brand is superior to all prior purchases.  The reason ... height!  While any collector can reach to eye level, most manufacturer's are happy to settle at belly + 1 foot.  The addeded levels allow for more efficient and effective storage!  
Would recommend to all those who's collection has gotten out of hand!
