Every gun shop I've been in lately has claimed all the cheap AR's are out of stock at their distributors.

Then again Colt's can still be had at just a couple hundred more than the cheap guns if you look hard enough and have cash for an incentive.

The Colt will retain value but will also shoot targets as well as any plinker yet be reliable enough for a duty gun for LE. To me it's a no-brainer but YMMV.
