Friend, consider moving that to $70 or a bit more. Under $50 means used leather or something that I wouldn't recommend.
For IWB, I'd heartily recommend an IWB holster from AJ Concealco. Take a look at it. I think it's about $70 - $80. I have 3 I think and love them. They're very affordable but high quality.
You can take a look at Don Hume but I find them to be thin and not the best holster. They're not quite "cheap" but they're close to it. Galcos are "ok" and are afordable but they seem to be thick.
I'd also recommend you take a good look at UBG holsters. His stuff is VERY reasonably priced for the excellent value you get. I have one of his for my K9 and it's a very high quality holster. I think his holsters are in the $70 to $80 range but check out his site.
Of all the places where you want to make sure you have quality, the holster is it! The fit, retention, and sturdiness are all crucial to secure and safe carry.
God Bless
