Kramer makes the best, but they are also among the most expensive. http://www.kramerleather.com/ On the other side of the spectrum there is Old World leather products. Their pancake style holster are some of the best value in the market place. The key to this or any holster is going to be fit and function. The Old World holster at about $25-$35, providing that it fits your gun and style of carry, is a excellent choice. They are distributed by Michaels of Oregon. http://www.uncle-mikes.com
You didn't specify what TYPE of holster. I carry a five inch 627PC in an IWB holster from AKJ Concealco. (Andrew did think I was a tad strange when I ordered it, he had to get a forming dummy as no one had ever asked for an IWB for an N frame). Since then he has sold about a dozen (last I talked to him) for various N frames (mostly snubbies).
