I have the same scope (since Jan 2011) & believe me, I have done as much research on EP's as any sane person should. I bought some cheaper Orion Expanse EP's due to impatience & not wanting to waste money on expensive EP's that may have not been appropriate for my scope.
I have since come to the conclusion that Televue are the way to go, they cost a bit, but in the long term, I believe will a good investment.
I decided on the following; a Panoptic 24mm (due to weight considerations) & a Nagler 13mm & 7mm.
I don't require glasses to view so the shorter eye relief is not a problem.
I must add that I have only decided to buy them this week so I can't give you any info on what they are like.
Here is a good link to help you decide on focal length & field of view of EP's:
