Here are all my eyepieces , every one bar the Celectron 31mm Axiom ( that come off NZ's 'Trade Me' ) and the 2x Powermate ( Bintel ) has been bought off IIS , over 6 long years ,, whew!!
.
A few $$'s worth but a lot cheaper than buying new and as I said the cost has been spread over 6 years .
I am happy with what I have now .
All these eyepieces work well in every scope I own .
