RE: Cheap Remington 700 at Wal-Mart
$314 is a good deal on a 700 ADL. I picked one up a few months ago at a Sports Athority for $304. I turned it into a .280 AI.
The new 700 SPS, that replaced the ADL, is still a good deal. I have seen them for as cheap as $399. The SPS has the hinged floor plate, like the BDL's.
As for the Model 70 discussion....
As far as I know, all post-64 Winchester Model 70's were push feed models. After about 30 years of making strictly push-feed models, Winchester brought back the Mauser-style extracter in the early '90's and dubbed them the Model 70 "Classic" models. The classic models came with a higher price tag too. Winchester still offered the push-feed varieties in certain calibers and configurations (like varmint models). The push-feed models were less expensive, and I can guess this is why so many chain stores decided to carry this version of the Model 70. In my opinion, the push-feed models are not a lower quality rifle, just less a expensive variation.
