I also like the protective display boxes posted above from videogameboxprotectors a lot. I have some for my SNES, N64 and various GB & VB boxes. They look great, and are worth it in my opinion.
I was also very happy to see that they now have some for slipcase VHS cassettes. I don't have many, but I wanted to protect the ones I have, and they fit perfectly. Most of the VHS tapes I've kept/collected are the various Star Wars releases, Indiana Jones, and Disney titles like Mini Classics, Sing Alongs, etc. I also have a Betamax Return of the Jedi tape that has the same size slipcase as a VHS, so that fit as well.
