I honestly can't comment on accuracy. I've actually owned five of them now, but never shot any of them. I really just think they look cool.
If I saw one for sale in the $900 and under range, I'd buy it. Anything over that is to much in my opinion. I've paid as much as $1000 for one before, coming out on it by the skin of my teeth.
If it's a stripped barrel (with nut and gas block), I'd probably pay $150 for it.
I hope this helps a bit. Good luck with your projects.
