Quality, Affordable, a lot of available parts, great replacement triggers, strength, and thats just what a lot of guys use. Gunsmiths like to work on them.
All that being said, until you get a Remmy trued, lugs lapped, tuned, Sako Extractor, square the bolt face, and all the other little things that you can have done you can buy a good custom action, screw on a barrel and end up with about the same amount of money when it's all said and done. The key word is "About", you can get custom actions ranging from $800 to over $1300 if you want. You can easy get $800 wrapped up in doing a Remmy action. I have a worked over Remmy action and it shoots just as good as a BAT, not as smooth but it is a shooter.
