Tikka is made by Sako and is a fine company. Don't worry about repairs, which would be rare. The Tikka if you get it, may become your go-to rifle and yes they are exceptionally accurate out of the box. As for the Remington 700 trigger, my gunsmith installed a Shilen in mine. Great trigger and cheaper than the ones you are thinking about. It breaks clean at a crisp 2 lbs.
