I personally don't like the Plossl design as the traditional design is not friendly to the eye being closer to the EP than the point at which you finally see the aperture stop. What happens is that as the head moves about, there is a huge "kidney bean" shaped dark area that occurs in the view and this is extremely distracting to me. Apparently most users that like the design don't get their eye that close to the EP.
I prefer Konigs (wider views but the design has a poor eye relief so the shorter ones do tend to make you put your eye almost on the EP) and Erfles (wider views but not as sharp at the edges, especially for older eyes). For an EP of about the same price as a Plossl is the Kelner design, especially the RKE of Edmund Sci. (they've been on sale for $40 an EP).
Actually, when it comes to EPs, get a fairly cheap set of them to cover all of the magnifications and then after you have that set, consider getting some particular EP sizes as higher quality ones as you learn what you want to see more of.
