I have three 5.11 belts and they are awesome. Of course I got mine free so the price was right too, but that being said they are great belts and I would pay for them in the heartbeat.
You are totally correct to grab a good gun belt, to me it made carrying so much easier and more comfortable, plus it gives a good platform for the draw. (meaning the belt stays put when the gun is drawn, it doesn't rise up with the holster/gun).
