Hi David
As a pretty green newbie I wouldn't put too much weight on what I say but I have a little viewing time through a 42mm GSO SV (65-68 deg ApF) & a 28mm William optics UWA (82 deg ApF).
Not having viewed through a Nagler or Meade UWA (wish I had) I can't give a true comparison between the higher end 82 deg EP's.
The 42mm GSO is brighter but suffers at the edge of field as expected of a budget EP, but for the money not a bad eyepiece.
The 28mm WO is sharp across the field but does seem to have a greenish tinge on fainter objects, the 9mm SWA version is the same though bright objects don't show any green tinge.
Jupiter the other evening was stunning, banding, sharp edged and the shadow of one of the moons on the surface gave me a real buzz.
Price-wise I guess it's more a mid range EP than high end.
28mm WO UWA approx $550
30mm Meade UWA approx $750
26mm Nagler appox $850
As I said before my inexperienced eye can't say 'go out & buy one' but I'd love to hear from someone who has had the pleasure of all these EP's.
As for your wanting a wider FOV...use the ED80.
