You can get a Boyd's wooden stock if you want your pistol grip to be thicker. There's a USGI fibreglass stock that's about $125-$175
The Troy chassis run about $1200 and there were the Marstar AKM stocks for $900 I believe.
The M14 doc composite stocks are really good, and priced at around $500 I believe. Recently the m14.ca guys brought out a chassis that runs about $600
I have personally found the USGI fibreglass stocks to be a great addition. My rifle saw an increase in accuracy over the Norinco squishy wood, and the grip area was thinner which really helped because I have small hands, kind of like asian woman.
