I'd go with the SPS. Contrary to what was said above, it does come with the X Mark Pro trigger. I have one and its there. Also, with that $250 price difference you can buy a different stock for it, like an Alaskan Ti style Bell & Carlson.
Got my SPS early this year so is either a '10 or '09 model I'm guessing. Just looked on their site and maybe they got rid of it on the SPS and are putting it on the more expensive rifles now? The SPS info doesn't say it is available, but when looking at the trigger page it says it is now standard on 700 rifles. http://www.remington.com/sitecore/content/Remington/pages/xmark-pro-trigger.aspxSame as on mine, don't even need to take it out of the stock to adjust it.
Save your money and put it towards a sako or at least a tikka. Sako 7mm mag with a nightforce scope..........oooooweeee. You'll be sniping you're game from the adjacent ridge.
