First thing I would tell you is don't be hung up on finding only a .270 Winchester. Be open to other chamberings like 30-06, .308, 7mm-08, 25-06, .280 etc... This will allow you to have many more firearms to choose from and the difference in performance in any of these cartridges will be minimal.

Second thing is don't worry too much what the stock looks like. If it is scratched all to hell but not cracked or broken in any way this is a plus for you as it will drive down the price of the firearm and you can refinish or replace it later. Just make sure that the barrel is in good shape and everything functions like it should and there is no rust pitting. A little surface rust is no big deal as it is easily removed and will drive down the price for you as well. Make sure to take it out of the stock and look at what you can't see.

If you find one in a pawn shop never never never ever pay what they are asking for it.

I would look in your local classifieds, gunsamerica.com, auctionarms.com, gunbroker.com, flea markets, garage sales, estate sales.
