I've got the Denk standards, and have been debating whether or not to upgrade to the Denk II or the Mark V. Now I'm considering the Binotron or the Mark V. Decisions, decisions........
Binotron sounds really good, but he has 26mm Clear Aperture prisms, while Mark V has 28mm! I really like my MkV 
Optically the Mark Vs are my front-runners. My concern is whether or not I will tire of constantly changing out the Glasspath Compensators. I know there can be some minor vignetting issues with the Power Switch, but the convenience of being able to change magnifications without switching configurations or getting up from the scope to change eyepieces is very nice.
My decision problem is that I'm very picky about optics, but I have limited time for observing these days, so convenience becomes more of an issue than I would prefer.

You can always use a Denk PowerSwitch with your Mark Vs. Here is how I did it...
FrankenBino
Eventually though, I was not totally happy with the Power Switch's low power setting so I got a Siebert 1.3X Multi Mag OCA and a few more bino pairs of eyepieces. I also tested the 1.7 Newtonian Glasspath Compensatoer but at 1.7X magnification, the less amount of wide view was not working for me. I now just change eyepieces and the 1.25x Glasspath Compensator stays in the Mark V's for the most part. The only time I remove the 1.25X Glasspath is when I need a little less magnification. At first I thought that it would be a pain in the rear end but it's not too bad once you get used to it.

Thanks Sergio. These give me some more possible solutions, but I'm actually leaning towards your suggestion of just leaving in the 1.25x and adding EP pairs. Appreciate the link and ideas!
