I have both the Imbel FAL and the Armalite AR-10B. A friend has the LAR-8 and really likes it, although I have never shot it. I love the Imbel, but if I had to do it again I would get a DSA.
Oh, and CProducts is making SR-25 magazines which will work in the DPMS. Armalite recently had a sale on their magazines at $23 each.
