Are you looking to buy both the belt and holster for less than $50? I think you can get one or the other for $50 but not both - if you are talking about having some, "quality."
I just bought a belt and holster from Crossbreed but before I did that I did some shopping around...
I stumbled on this website
http://www.qmuniforms.com/ - you just might be able to find both your belt and holster around $50, or little above
The other thing is buy one at a time - Desantis has some nice stuff.
Good luck!!
