Want to make your inexpensive dobsonian reflector perform like an instrument that costs twice as much? The Televue Paracorr is the best addition you can make to your reflector's eyepiece collection. Look through a typical reflector's eyepiece and you'll see a nice central image, but the closer you get to the edge you'll see an effect called coma. It's particularly bad with inexpensive, fast (f5.0 or less) dobsonian reflectors. Put this corrector in front of your eyepiece that'll all go away and you'll have nice round pin-point stars. :-)

Televue 24mm - 8mm Clickstop eyepiece
Just bought a Televue 24mm - 8mm clickstop eyepiece while at the Mt. Bachelor Star Party. While it's really a Vixen eyepiece (Orion sells the same eyepiece without the clicks) it's still very convenient. Very nice to stuff one eyepiece in your pocket instead of carrying a Pelican case out to the dark sky sites!
A bit soft at the edges and doesn't have a super large field of view, but as a zoom it works great.
