If money's not an issue, the M1A is very, very, very nice. The FAL is also, but not quite as accurate.
If money is slightly tight, I'd look at the DPMS .308 AR-10 style rifle.
I owned a PTR-91 and sold it. I'm a big guy with big hands and the ergos were still awful, like it was designed for Paul Bunyan or something. It also requires an extremely strong left arm to open the bolt if you let it slam forward (as you should!) and fully lock. It throws brass about 40-50 feet and crimps the case mouth in the process, so any empties you find are probably not reloadable. And recoil was stout for a .308, though it varied noticeably depending how clean and oiled the gun was.
The G3 design is reliable and fairly accurate, but IMHO not the best of the .308 options. It also sells for about twice what it should, since it's no harder to build than an AK-47, and probably even easier. If you do the G3 route, the PTR-91 is probably the best quality at any price, and definitely the best value.
