The Taxis project was just under $1000 before paint and homebrew hardware until I replaced the shimmed factory trigger with a Rifle Basix. Maxis was a bit less. Depite opting for a recoil pad and pepper laminate stock instead of a normal plywood model from Boyds, the barrel from Apache cost far less than a Shilen and the host rifle was a smoking deal. The cheapest build was probably my first Axis (for which I don't have a stupid nickname). Even with its "bargain barn" Boyds stock and Battlezone scope, the total cost was just under $700.

This is with the recouped funds from selling the unused parts, of course.
