Safariland makes a copy of the Milt Sparks Summer Special IWB holster.
You can get it on Amazon for $42.
You are going to have a hard time beating that for anything that is going to be decent. Many times guys don't want to spend the $$ on a decent holster, then what they end up with is something that is not comfortable, or does not hold the gun well, or does not conceal well, etc, etc. Then they end up just taking the gun off and leaving it under the seat of their vehicle or wherever and telling themselves that they will just go get it when a problem arises. The problem is that it never really works out that way.
A good belt and good holster go a long ways toward making sure you carry the gun every day.
