I use 2 kinds both look good, but are fairly inexpensive. The first is from Ikea. There are three racks in this pic. They hold 302 DVDs each and are around $50.
The second is retail slatwall. Prices vary based on options for the wall itself (search on slatwall), but the shelves hold around 75-80 discs and are about $8 each. This is what I will be using in a new home we are building. Some of the shelves also work with pegboard.
