What do you think of the 8mm BST Explorer Dual ED "Starguider" as an alternative? They sell very well, so I guess it is a good product?
OR this from Ozscope?

Another possibility is this eyepiece:

My preferred choice is the 8mm BST Explorer Dual ED "Starguider" right now. It seems to be popular and has good specs.
