if solid wood, i'd look at richards (same site as doubleA specified), they usually have pretty good close-outs on remington 700's and winchester 70's. If you'd consider a laminate, I'd go to boyd's. You can get an unfinished laminate through boyd's for about 80 bucks. I just got a ross thumbhole for my a-bolt and was surprised how easy iot was to finish inletting the action.
