The horsehide I bought from Beltman was about $115. With a military discount is cost about $90. Delivery was about 8 weeks but worth it. His belts can cost more if you need the reinforcement liner. I don't recall exactly what it says on his website, but is your waist is under a certain size you don't need the insert.
The 5.11 Tactical belt was $40 on sale at the Fort Sill PX. They're usually $50. I wear this belt with cargo shorts.
I went with a cheap belt for years and thought they were fine. I only became a believer in true gun belts about six months ago.
