I have one in 30-06, love the stock as is, though a better recoil pad is required. The trigger I just had done finally, cost me all of $12.50 by a gunsmith, he didn't mill/grind a thing, just a quick polish job and replaced the trigger spring with a lighter one. It went from roughly 7# to a nice 3# in 15 minutes. It is listed as a DIY on RugerForums.com, most are just using a ballpoint pen spring as a replacement.
Depending on what type of material you want, Richard's MicroFit Stock's is having a sale on some of their 99% drop ins.. Lams $80 and basic walnut @$60.
