I don't like the IWB stuff so much.
Fobus hoters are great. They can be found on Ebay for under $20. Hard to bet.
I'll admit that I own a Fobus, and they have their uses, especially early on when you have no money, or no knowledge. I think anyone who has been around (I haven't as much as some) will tell you that Fobus holsters are not great, they are mildly OK. There are other much finer holsters that can do the same thing (Blade-Tech?). You are talking about more $ though. I'm not saying this to start a war, I'm saying it because they are like anything...they have a place, but they are far from top of the line.
Take a look around for the video of the guy disarming a guy with a Fobus. He just walks up, twists it back, breaks it off and walks away...about 1 second tops. I'll find it later when I get off work if you can't.
