The Colt Double Eagle is a rare bird, and oddly enough I saw a used one in our local Gander Mountain THIS WEEK!
Your FAL choice is honestly VERY VERY hard to argue with. If I were stronger or ammo was lighter - I probably wouldn't own anything else!
Architect, the DE indeed a rare one and I found it laying used in the display case at Grice Gun Shop in Clearfield Pa about 10 years ago. It had only been there a day or so and I knew it wasn't going to be there for very long. Needless to say, I jumped on it. I'll bet that one you saw at Gander Mountain was pricy.... The FAL bug bit me about 15 years ago and oh baby, it bit hard. I started out with a Century L1A1 that wasn't very reliable. To make a long story short, I had it rebuilt on an Imbel reciever and she really shoots now. I bought 2 more Gear-logo Imbel recievers and had a South African R1 built by Arizona Expert Arms in 2000 then a year or so later I found an absolutely beautiful German G1 kit. I had AZEX build that one for me too. I have AR's but the FAL is my "go to" rifle.
