If you are thinking economy, the likeliest suspect is the Bushnell TRS-25. Sometimes people get a lemon, but a good one will stand up to turkey loads. I bought through amazon so I could send it back for exchange easily. Good thing 'cause I had to. The second one is fine. Install on the vent rib with a mount like Aimtech Ribrider.
If more serious, better micro dots like Holosun or Leupold or Burris FF IV with shaped dots will be clearest and have long battery life. I'd mount those on the vent rib, too.
A third option is a big payload of small TSS pellets loosely choked. A three foot wide pattern with plenty of pellets in it is hard to miss with at normal ranges.
