How much woodworking experience do you have? How much free time do you have? To reshape a Boyd's stock I'd figure on at least 10 hours, probably 20 hours, NOT including the finishing. For a CMPicon stock you just need to sand to whatever grit and use whatever finish you want. You can get a stock from Dean's that is fitted unfinished, which means you have to do the final sanding and the finishing, and it's 175 dollars plus shipping.

FWIW I've got a Boyd's, a CMP, and a couple Dupage 2nds stocks, the CMP is the least amount of work, the Dupage is the most inexpensive but had flaws I needed to fix, but the Boyd's was the most rewarding. I was also able to shape the pistol grip so it fit my hand a bit better, something that really couldn't be done with the CMP stock(less excess wood). Hope this helps.
