Great quality "semi-finished" stocks here:

You will need some basic woodworking skills to finish the inlet and finish these but not hard (if you have some patience and a bare minimum of skill).

Boyd's also sells prefit/prefinished for some of the 99's - you need to pay attention to their specs on tang length, pistol vs. straight grip, etc..
