I am thinking of buying a few and I was wondering which ones everybody recommended.

http://supermediastore.com Has some good cases, They have cases that hold 8, 12 and 24 which saves a lot of space on the shelves. Half the fun is making your own labels. :D Here's an example of how I use them.

When my mom finds me DVDs at the thrift store that have no cases she sometimes uses white envelopes to put the DVDs in and it works for me because I never have to worry about cracked or broken jewel cases because that's one thing I dislike about my music or DVDs when I store them in boxes. If you are also looking for a place to store your DVD cases I recommend going to Target and look for under the bed organizers and they also will work. My mom got me some organizers to put some of my movies in and they fit perfectly under my bed and they are easy to open and store your DVDs in very well
Hope this advice helps you Regulus
