pwrstrkd,
As with all gun recommendations, you need to communicate two(2) all important things;
1. Intentions with the gun (match shooting, hunting, Self defense, etc)
2. Price range
You indicated that you dont want an expensive gun as in AR-10 pricing, however, without knowing your price range its tough to know what you really mean. AR in 308 can be had for $900-$5500...depending on whether or not you are willing to pay to be tacticool. You can find used DPMS 308 for about $750-$850 if your not above picking up used rifles.
Once again, respond with a wee bit more info, then you can get intelligent recommendations on what may fit your needs the best.
