As
@mdwest said it really depends on how much you want to spend. You can find stocks sometimes for well under $100. I found one last year (before I bought this barreled action) for $40 and of course it was gone when I went back after buying this. Stocky's, Boyd's, B&C and several other after market stock makers all have offerings. You can also go complete custom.
If someone owns a screw driver, sand paper, a few other tools, and wanted to pinch pennies by shopping around, you could probably finish this for around $200. Me personally, I'd spend a little more, add sights, nicer stock, bottom metal, etc.
