I've just recently got a myastroshop.com 2" ultrawide 30 mm eyepiece ($129) with 80 degree view which I'm pretty happy with, there's some distortion at the edge of the view, but it's good for about 80% of the area. Optics seem pretty decent for the price, haven't seen any internal reflections and it's nice and clear.
A wide angle 2" eyepiece like that gives you a fantastic feeling of being out there with the stars. it's also good for big nebula and for locating small objects which you can then swap to a smaller focal length eyepiece for.
$1000 eyepiece will obviously be a lot better, but for $129 it's good.
