I got a bunch from ebay from the seller below:

Thanks for the info.
I just couldn't figure out what the acryllic risers were called. It's a huge help since I have about 18"-20" of depth in each shelf where I'm displaying figures and I can easily get about three rows.
I also went with the Billy because I'm thinking I might be ably to fit in my Jake Sully in with some of my other figures
