Even cheaper are the GSO superviews from Andrews 15mm and 20mm $39 and 30mm 2 inch $49 , all 68* fields .
I grabbed one of the 15mm's for a friend up here a while ago and I was very impressed with its performance , very , very good . I don't know how they do it for that price ,
.
Others have said the same thing about these eyepieces here at IIS over the last year or so .
