Depends on what you are looking for and how thick your wallet is...
Boyd's & one of the Bell & Carlson synthetics are the easy least expensive average quality choices.
McMillans and Manners are better & mucho higher $$ choices in synthetics, and offer broader choices in TAC and Precision Shooting stocks, although McM's has a wide spectrum of hunting stocks too.
Richards Microfit, Fajen and others fill in the gap for "moderately" 90% finished wood stocks. Serenghetti's makes my heart go PittyPat, but I don't see the logic on spending more for a pretty peice of wood, or a McM's custom fill than I did for the rifle.
Let me win a 7-8 Lottery or inherit "well" and I'll have a different perspective I'm sure.
JMHO & YMMV
