They've gotten a lot better but I think they're still around $750-$1000 and for a little more you can get a better rifle.

If I were going to but an AR-10 and only had that much to spend I'd just get the Smith & Wesson M&P 10.

This one is a good deal. You get a better lower & upper receiver, better bolt carrier group, and better barrel than the PSA plus you can upgrade to a free float rail from someone like Centurion Arms for ~$200 and get a barrel from Criterion for ~$300 and have a great rifle for around $1500 once everything is done.

Ignore the "out of stock, no backorder" message because they get them in pretty frequently.
