CombatKit do stuff in DPM and is high quality. It's available in the UK from Tactical Quartermaster. He offers a good service but orders the kit in on a montly basis so you might have to wait a bit, but if you drop him a line he'll keep you up to date. Some one else worth considering is Warrior Webbing. His vests are high well made, not too sure about the pouches though. CombatKit would get my vote for what it's worth.
