I know nothing about FAL style rifles, but I do know a little about some of the other popular .308 battle rifles.
With that price range, I'd say the PTR-91 G.I. model is probably your best bet. Before the Newtown panic set in they were selling for around $900 new, and they are one of the better G3 clones out on the market.
If you save up a couple hundred more, you may be able to get yourself into one of Springfield's lower end M1A's. or, if you are looking for something more modern some of the lower tier .308 AR's from Bushmaster or DPMS also fall into that price range.
