Intes Right Angle Finder $60 plus shipping
I got this with my MN76, but I have never used it. A bit heavy and I don't like the mirror-image view. Hence the sale.
Multicoated. Solidly built. Has cross-hair reticle that can be used with a illuminator. Eyepiece has helical focuser. This is probably the 10x50 model, as I measured the exit pupil to be 5 mm. Intes also sells a 8x50 that seems to look identical. ITE sells these new for $145 to 175.
