The little tools used to adjust the trigger can be bought online.
I have owned several savages with the accutrigger and wouldn't consider buying an older model savage without it. The accu-trigger started something in the gun industry that the rest of the manufacturers are just now trying to catch up with. My buddy just bought a Remington SPS Tactical and it's got the new trigger in it and it's a fine trigger, but it came about as a result of the savage accu-trigger.
I've shot the standard accutrigger and the target model accutrigger (red blade in trigger instead of the stainless one), timney drop in triggers, rock river two stage triggers, mil-spec and a few other triggers and for me I like the regular old accutrigger as much if not more than any of the rest. Last night I put a different scope on one of my savages and dry fired it a couple times. The rifle has almost 2000 rounds through it and the trigger on it is still simply outstanding
