Hi Matt
If you haven't already done so, take a look in the Eye Pieces forum and read some very helpful threads there.
You haven't mentioned what focal length you are after.
Different focal lengths behave differently in fast scopes without a Parracor and for that very reason I do not own the same brand eye piece throughout my focal lengths. If you're not terrible fussed by edge performance, then that's great.
Regarding Naglers (I don't own one, but have been told this several times), if you wear glasses, forget them as the eye relief is very tight. Even though I don't wear glasses to observe, for comfort, I will only employ eye pieces with 20mm eye relief (aye! a rarity to find) across all my focal lengths, now finding one that does that and performs perfectly to the edge in a fast scope (mine is f/4.7) has always sent me walk about on long drawn out missions, but in the end I do manage to find what suits my needs beautifully. Even though it costs me a whole of money, I actually save money in the long run as I'm not buying junk eye pieces which I have to keep replacing because they don't perform as well as I'd like.
A good quality eye piece will give you great contrast that will help you resolve many DSO objects - vital for intense observations at the eye piece. Many moderate range eye pieces tend to be very bright making contrast to get some detail next to impossible. As an example, the difference between a Meade SWA5000 and a Pentax XW is jaw dropping on Jupiter - and even more amazing, I could see a ton more detail and colour at lower magnification with the XW10mm than I could with the SWA at 6.7mm. So there's a perfect example for you. The seeing was good, so higher mag. would not have impacted the use of this ep, and I do find 7mm is often doable before seeing conditions dictate.
But anyway, my point is, the better quality premium eye pieces will provide you with great quality. Meade, Baader, Celestron etc in my opinion would be moderate range eye pieces.
I guess it's just how fussy you want to be I suppose and how much money you are willing to part with.
Just making sure that you also know that the ES eye pieces are very very heavy on a dob. The 24mm ES weighs in at 940g!!!! And don't even think of barlowing it. On your 10" dob, that is likely to cause balance issues. Note however, that the weight varies throughout the focal lengths, so again, depends what you're after.
Meanwhile here is some reading for you on the ES.

I feel that this thread would have gotten more attention it were placed in the Eye Pieces Forum.
Meanwhile Matt, all the best in your search for your eyepieces.
