I've got a remington 700sps tactical in .308. I bought it for $900 from a good guy on this forum. It came with a good scope and bi-pod on it. If I were to go buy the scope and bipod new, I'd have spent about $500, which in a sense means I bought the rifle for $400.
just know what things are worth and be patient, (or don't worry about the budget, and get something right away!)
