One of my Dobs is a 10" Sky-Watcher Collapsible. ...... My scope came with two caps.

They no longer do.

...And last thing I want is to see a bunch of shower caps all over my scopes
When I found out the newer SkyWatcher collapsible Dobs came with only one dust cap for the primary half, and just a shower cap for the secondary half, it was kind of a turnoff for me

I hardly ever use the top cap to begin with, basically only when the scope is in storage, so for me that would be a very minor issue.

Dave is doing it right... a scope in use gathers no dust!

Just sayin'...

Humm..

Have you ever actually used a scope with "correction tension springs?"

Of all the systems on commercial Dobs, it's my favorite, it mimicks the large altitude bearings of the premium Dobs. My 14 year old GSO Dob uses the system.. I use it at magnifications up to 822x with good results..

Nothing in my house can ever claim to gather no dust. It might be a disadvantage of the "all windows open"tropical environment is the amount of dust I get inside my home. I store My Z114 reflector stored with its cap in a plastic bag in a closet in the 2nd floor, and laid horizontal, still collects dust!!

No, I haven't. I've only used Zhumell altitude bearings on a mini-dob (Z114).

I have, and I found them to be horrible!
Another vote for the Z8 from me. I had one of these, and it was almost great right out of the box. With all of these scopes, you'll need to replace the primary springs. As mentioned, the knob is no big deal, and you can build your own dustcap.
