ChrisAU: My LGS has a previously owned (won at the NRA Banquet) Kimber Hunter for sale. The gun is unfired and comes with all paperwork and box - I was told it never left the shop but was consigned there by the winner.
It is the stainless model with removable magazine feature and the pleasing tan/beige fiber-glass stock. Sadly it is in caliber 30/06 which is not on your list (as yet?).
The asking price was IIRC $625.00 - no sales tax in Montana.
If you are interested the shops number is 406-683-9844.
Good luck with your project.
Hold into the wind
