If you are still looking and if you would like to add another suggestion to the mix, the local shop just picked up some new bag-style targets this past winter. They were using block-style targets up until this point but decided to pursue a different route. I don't have the specific info for you now but can find out when I head down later today. From memory, they are about 4 foot long by about 2 to 3 feet high and 2 feet deep with a burlap style outer covering and some form of wood chip material as stuffing.
They stop arrows very well and durability has been good so far. After they are broken in a bit then arrow removal is not that much of a concern though initially they are a bear...
