So... I've built various ARs, bolt rifles, and other things. I am an engineer by trade and education, so I am into those things.

I've never had an AK, and would like to add one to the arsenal at some point. So, the AK nurds of the herd, would you suggest I build or buy for my first AK? Also would like to hear some pros/cons, and perhaps some price ranges for nice but not extravagant AKs (oxymoron?), built or bought?

Whatever your opinion, any comments you have to steer me in the right direction for research and planning are greatly appreciated.
