I have 2 standard models that I bought in 02'---one has a TRW barrel and the other has a HR barrel. The one with the HR barrel also has a GI trigger housing and thats ALL the GI parts between the 2. I picked them up when I heard SA was running out of GI barrels, figuring (at least in my opinion) that the barrel was the GI part that matters most.
They have performed flawlessly thru about 800 rds. each--so they're really just getting broke in.
I prefer my FAL's and AR's for funtime shooting, and would probably grab one of my FAL's if I was heading out the door and could grab only one rifle--But would not feel lacking at all if all I could have was a SA,inc. M1A.
I think SA,inc. M1A's suffer from a bit of a bad rap due to the fact when someone has a problem, they tend to tell everyone out of frustration (and rightly so)--but most people that get a good one don't think much of it or say much about it on the forums because that is EXPECTED when paying 1000+ for a rifle.
The only repro part I feel is a legit concern for replacement may be the extractors--alot of horror stories seem directly linked to this relatively cheap part.
my 2 cents
