Depends on what you want to spend. If you're serious about 3D you're looking at Delta/McKenzie or Rinehart. The Rinehart's are a higher quality target and will last longer but they also cost more. I've got some of both.
Just purchased glendel buck today. Had $50 gift card , free shipping, and $20 mail in rebate. After everything $88.
Ditto. I got a second one in great shape off CL recently. Very durable and reliable product. The one on CL came with an easy mounting device so I don't have to pound stakes into the ground.
