The SpeedDot which I bought @ 8 years ago came w/ a screw-on sun shade which is a real bonus, especially on very bright days. I have owned, and gotten rid of, one of the "cheaper" red dot scopes, and, in my experience, like on all optical devices, "you get what you pay for." I have assisted several friends and hunters upgrading and mounting higher quality red dot scopes after they actually compared the optical image. field of view, and light gathering ability of some of the cheap scopes w/ higher quality red dots.
