SOE has the Specter and BlackHawk Line of Instructor Belts. Prices range from 900 to 4,500 depending on the design and load bearing capabilities.
They also have an excellent line of Liger belts.
As for the Wilderness, I saw some in Final Option MCS, but not sure of the price.
For a leather belt, get a Bianchi from either Jethro or Hahn.
