I would check out Atlantic Arms for some deals. Personally I'm not fond of Io or DDI. I'm sure Io probably has better qc and uses better quality by now though. As far as DDI goes for me it's a US company trying to make a com boc rifle, they cant seem to get it right. The US built ones didn't go by the commie specs, ie they used different steel and hardness specs so their not as solid the commie built ones. You can find decent ones built off parts kits from reliable builders but it's gonna cost some coin.
The only factory built ak's I ever had was a Poly legend and a mak 90, all my other aks I built myself.
