I have lucked into a few discontinued diamonds.
The 21mm (non-LX) Ex-Cel was a steal at Telescope Warehouse,
and probably the only one in the line easy to place the eye over.
I won't push my luck on other non-LX's, though..
The 17mm Orion Explorer-II is amazing, and its construction
internally resembles a Clave-Plossl
far more than a symmetric-pseudo-plossl..
I had a scope handy at the swap meet at the time..
I got 3 for $7 each just before the table closed.
I wonder if anayone gave it a good looking through before...
..it was in a "comes with" package. It is a diamond, though.
