Thanks to everyone who replied to this question.
It looks like I will have to make a comparison myself, however finding the two different ones to observe together with the same "seeing" conditions will be difficult.
It would be nice if I had the money for the Denkemeir ones. They sound like they are the choice of the bino-viewing world.
However I also think that with a small budget, much enjoyment can be found in the more economical types. At least I hope so....
And yes, then two lots of Eyepieces come into the picture...........
Hmmmmmmmmm, where does one stop.........
Once again, thanks for the comments....
