I should have said positive reports rather than reviews - search cloudynights forum - I recall one guy saying the HD's were as good as his Sterling plossls. I haven't seen reliable reviews which is why I suggested asking Bintel.
Some of the newer Chinese eyepieces are very good though, requiring back and forth comparisons with top shelf eyepieces to detect differences. I have Astro-Tech Titan ED II's and a 22mm AF series that are very nice. Tiny differences between brands can become significant for experienced observers under good conditions but it's not necessary to spend a fortune to get good eyepieces these days. Of course there are plenty of poor quality eyepieces still around too.
