The cheaper binoviewers sold by william optics/stellarvue/burgess/university optics work quite well so long as you don't get a miscollimated unit. I have a stellarvue bino that I think is worth having even if it was only ever used on the moon - the view is much nicer through two eyes. Fronteir optics sells a good selection of bino's with prices now listed at the bottom of the page.
