William Optics Ultra Wide Angle 82 degree 2" eyepiece -
$250 + shipping
This was my favourite eyepiece with the WO FLT-132 refractor that I used to own - very sharp stars across the huge field. Not so useful now that I have a 10" Dob for visual observing (coma), plus it's difficult to balance on my Dob.
It's optically in perfect condition, no scratches, just has the usual dust/dew marks.
I'm open to trading this for a 1.25" TeleVue 24 mm Panoptic eyepiece (for my small refractor).

Baader Multi Purpose Coma Corrector -
$150 incl. postage
I recently bought this from another IISer with the hope of fixing the coma, but never actually got around to using it (and also didn't have any spacers to adjust the MPCC-eyepiece distance).
It apparently works great for photography -
