The 5.11 Tactical series has a couple in the $100 price range, designed by Steve Tarani. I own one of those as well. You can pick the Journeyman model up for $40 +S&H from lapolicegear.com.

I'm a happy fellow. This afternoon, my Emerson CQC-7B is being moved to my left pocket.

My right pocket is now home...

I use the wave feature almost all the time. About the only time I don't use it is when I'm handing it to someone. Most of my jeans have the rear corner of the right pocket a little jacked up ;)

Emerson CQC-7B with wave opener. I don't leave the house without it. If I travel it's in my checked baggage.
