After a long hiatus I am getting back into astronomy. Sky And Telescope
magazine is completely different from what it was back in the late 50s
and early 60s. Believe it or not, the most confusing thing that I find
today is the advertisements for telescope eyepieces. When I got my first
telescope there were only a few types of eyepieces. I'm not sure of the
spelling or the exact names, but I believe they were the Orthoscopic (?)
and Hyugens (?) eyepieces (correct me if I'm wrong) . Today I see adds
for Nagler, Wide Field, Plossl, and Kelner eyepieces. 

What I would like to know is how do all these eyepieces compare in price
and performance. Which ones are suitable for high or low magnification,
field of view, etc. I have also heard that some eyepieces work better
with a refractor than with a reflector. What is your personal
preference? My applications are observation of the Moon as well as the
brighter clusters and nebulas.
