Doubt you really had your action "completely" trued for $100 Cdn. You probably had front of the receiver trued. Lot more work that would have been done to have an action completely trued and blueprinted to be remotely close to a custom action. Yes, you spent less but you have way less also.
Most smiths quote $250-300 for that work and that does not include sleeving the bolt to get you to where you are close to a custom action. There is another thread going right now just about that very thing and lot of smiths quoted prices.
Used Rem triggers are $25-40 at most gunsmiths and ebay and complete new trigger adjustable trigger is only $100 or less.
Hope you "kissed" the guy(s) that paid $225 for rem SPS takeoff barrel and plastic stock. Rem takeoff barrels are normally $50-$75 max and used Rem plastic stocks never bring more than $50 on a good day.
is another link for $600 custom action
