There was a time when buying a Sendero meant getting an accurate rifle - but that ws years ago. Today, it is a crap shoot. If accuracy is what you want, then buy a used action and spin on a custom barrel. You can do this for little more than the same as the cost of a new Sendero. Least expensive route would be a Savage action and a pre-fit barrel. Next step up would be a Tikka action (my favorite) with a shoulder pre-fit barrel. Just about any stock will do for the short term and still get you an accurate rifle. you can later upgrade the stock as money permits. Your focus needs to be on the barrel and the scope.
