Tim, don't kid yourself. the FAL has no advantage over the AR, in terms of practical use or collectability with or without an obana.
For someone in God Bless America, you might want to think about training, not just hardware.
The colt 6920 is as worry-free as you can get, and you can use it in any of the quality carbine classes out there. You will get a suboptimal training experience if you bring a FAL.
Seriously, you should consider that there are a *^%-ton of english-speaking professionals USING the AR/m4 at the moment. When you put things into large-scale with people who communicate, you start to learn things. important things.
That base of knowledge does not exist in the US or probably anywhere for DSA FALs. It doesn't matter how many internet posters have a beautiful specimen in their safe; it doesn't generate quality operational experience. That doesn't mean some goober won't give you twice what you paid for it after the obana, if that's all you want.
I won't bore you with the litany of ergonomical advantages the AR has over the FAL, but the cost of ammo is important. I'm sure you've already checked and found you can buy LC 5.56 for about the same price as wolf 7.62. not to mention, you can get 22lr conversions for the AR and shoot all day for $14.
Quality AR mags are plentiful.
Spare and replacement parts are much more plentiful.
Quality aftermarket parts are ubiquitous.
I'm not saying the FAL is a "bad" gun, or that DSA doesn't make a quality product.
Think of it like this... Honda made 16+ million civics that ten million people drive every day. Winnebago makes what? 10s of thousands of vehicles that people drive twice a year? I'm not saying a winnebago is dog doo. I'm just saying a rational person, especially anyone with an engineering background, would not expect one of those mfg or surrounding industries to have worked the bugs out as well or be as efficient as the other.
And I'm not just talking about the military (as if that weren't enough). Go to any tactical rifle or 3gun match. If you want to learn how to run a FAL efficiently, you're going to have to figure it out yourself.
