Nagler or Pentax

Hello all. I have a Meade 12 LX200 GPS UHTC and the Meade eyepiece set. I will be selling the Meade set and a C-8 that I have to fund a couple of premium eyepieces. I have read many reviews of the Naglers and Pentax eyepieces. There seems to be a consensus that the Naglers and Pentax eyepieces are about equal with perhaps a very slight nod to the Naglers (indicated by some).

I am an intermediate level amatuer and for years have always thought of the Naglers as the best, but I also was always swayed by those glossy Meade ads--so my naiveté is clear. Is the price difference between the Naglers and Pentax eyepieces worth it? There is the additonal 12 degrees of fov, but all else seems to be about equal. I am looking to buy a 20 Nagler or Pentax or perhaps a 17 Nagler for use as a medium power eyepiece, but still somewhat for general use, and perhpas the 31 Nagler or 30 Pentax for lower power deep sky stuff.

Any help is really appreciated. And, some day, when I move from intermediate to more advanced I will answer questions instead of being a pain and keep asking them all the time.

Thank you for any help.

Gregg, I don't think you can go wrong with either eyepiece at F-10. If you had a faster scope such as my 16" F4.5, I would recommend the pentax eyepieces as they have no discernable aberrations at the edge of the field at moderate focal lengths. For example, my pentax 10.5 eyepiece shows a star at the extreme edge as a point with no pincushion,barrel or lateral color aberrations, coma or astigmatism at F4.5. Most amateurs don't believe this until I show them the image of a star at the center and then at the edge of the pentax unit and there's no distortion at all. At F-10, you might enjoy the larger field of the nagler but the 65 degree apparent field of view of the pentax is still quite nice to see most objects.
