Thank you for all the info. I was looking for a Costco, but nothing in my region in Ohio. Couldn't even find it on their website, because they only list stores within 100 miles of where you live, and nothing came up. But it certainly would have been my first choice, Sharkbait.
Went to Sams and purchased it. I hope they will be comparable!
Thank you for the info on the optics, Nigel. I suppose since this will be predominantly used for classroom and the court system, the sealed optics may not have been an issue afterall.
