If its a rifle that you want resell later down the road don’t go to low end you’ll never get rid of it .
I find it easier to resell less expensive guns.
Absolutely. You will always be able to sell a PSA 308 for $600. It's a whole hell of a lot harder to sell a $2k AR. Just look in the classifieds....308 ARs for under $700 sell in a week, but there's a LaRue upper that's been for sale for a month, and that is pretty typical.
PSA makes good stuff, I would buy one in a heartbeat if I needed a 308 or 6.5. I have a bunch of their AR15's and they all work great and shoot well.
