Lots of threads on eyepiece choice.
Here's one that discusses them:

I use Naglers and I'm happy with them.
From what I have heard the Pentax XW range is second to none, but they cost quite a bit.
One range to consider is the Vixen LVW, but they're not lightweights.
I haven't heard a bad word said about them. I almost bought a set myself. Many users say they are sharper than the equivalent Naglers.
Baader Hyperions are also pretty good and are 2" throughout the range.
Price does come into it. A set of premium EP's can add up to much more than the scope cost. Good luck, and having a look beforehand is always a good thing before buying premium EP's - star party perhaps.
