I was thinking of just getting a large 24"x24"x34" box from home depot for $18, and 1 inch x36inch length wooden dowel for $8, carving out half circle indents on top of box to lay the dowel across the top of the box. Cut out one front face of the box. And hang 2 bath towels over the dowel to catch/slow the projectiles.
Just got mine. Agree with your 'complaint' that the target is very deformed when removed from the carrying 'case.' Hopeful it will improve with time, but not holding my breath.
