RE: Which Rem 700
A model 700 is a model 700 as far as the actual gun itself goes. They are all the same except for stocks and other cosmetic differances like polished metal, engraving, etc... At least until you get into the custom shop guns.
An SPS is going to be a good "work horse" rifle that will be able to bring home the meat year after year and you won't have to worry about banging up the stock like you might on apretty oil finished stock.
