Help with choosing a display case

[Mcshank]

So after seeing a few members here with nice ways to display their collections, I figured I might as well get a display of my own. Right now my knives sit in an old headset box. I want something kind of like this http://zt.kaiusaltd.com/gear/gear/zt-countertop-display . I would also consider other ideas such as an end table with a glass top. I'd like to keep this under $100 if possible.
