I got my first one used for $99. Thousands of gophers have met their doom as a result. Back then you could buy a brick (900) of 22LR for $10.
In 2004 I picked up a Butler Creek bull barrel and stock from a sporting goods store that was going out of business. Paid $59.
My latest 10/22 project was a scratch build. Still need to get it anodized to give it some durability. Got all my parts from Midway USA.
Mig welded the aluminum together.
