Have heard very good things about the Rhinehart targets. Looking at getting one myself for my next target.
I use Bone Collector bag target for field points and it stops arrows really good, Heavy at almost 30lbs but arrows are removed with two fingers.
For broadheads I made my own to practice with. Nylon mesh bag similar to burlap bags filled and packed tight old rags and shirts. (remove buttons and stuff) Seen it stop my Grim Reaper practice head, and my buddies Rage practice head at an inch or so. With regular broad heads they go in 3 or 4 inches and are a pain to remove though. Can't complain for free though.
