which ethos would you buy?

Right now I am leaning heavily toward the 13e. In both examples the 18mm gets sold because I have a 21e now and don't need the 18mm.

The 13e is an amazing eyepiece! In my experience with a 12 inch dob the 13e will see more use than the 8e and would make a near perfect companion for your 21e. You are headed in the right direction.

Anyway, it sounds as if we are of one mind. I am working enough to afford it so why not?

I have to agree with Stephan and say the 10E is my most used eyepiece in my 14.5" dob. With it's 2mm exit pupil is seems especially made for observing galaxies from a dark site. If I was to do it all over again (with gained experience) I'd choose the 21/10/6 progression with exit pupils of 4.2, 2.0, and 1.2mm respectively.
I use my 20mm 100 AFOV ES the most, followed by 10mm 100 AFOV Ethos, followed by 3.5mm Ethos the least. Not mentioning my 82 AFOV but I tend to use the wider ones more as well, with my 17.5" f4.1 dob.

So what if for the next year supper is a continuous string of beans and rice, the monotony occasionally broken by splurging on some Ramen noodles.

I think this last plan may be much better. I know, from using one, that the 6e is a great eyepiece. That also is one less sale I would have to do. So here it is. Buy the 13e now or soon, then buy the 6e in the future. Keep the 9mm. The 6mm is slightly larger than a 1mm exit pupil in both of my scopes.

+1 for the 13mm, with my 8mm just behind it for usefullness.
13mm. The first and the best.

All of them.
I am happy with half of them.
The 8E and 10E don't seem so useful with a 9ES120.
Never found a need for the 17E sitting between the 13E and the 21E.

It is funny how my observing attitude has changed so much in the last few years. I initially thought that eyepieces should cost some fraction of the telescope price because that was what I had read. I have since changed that philosophy to, eyepieces can be used in more than one scope and can last a lifetime so why not buy the best you can afford? I used to get so upset every time I asked about eyepieces and someone said to buy a TeleVue anything. Who would spend that much on an eyepiece ?!?? Now I am considering buying more ethos.
Here in Always Cloudy western Washington, we have a limited number of useable nights and some would say that it is a waste to tie up so much money in this hobby. I say make the time you do get the best it can be.
