Rich, optical devices like the Farrsight are most certainly worthwhile for those who use them. Farrsight is no longer in business but an outfit named Merit makes a similar, if a bit more complicated, device: http://www.meritcorporation.com

I'm sure you wouldn't have a problem selling the Farrsights you have if in good shape and priced reasonably.
