Well said Mark and I appreciate you voicing those 'issues'. I do have reservations about the marginal increase in (utility) capability against the price point. In terms of portability it is mandatory (in my case) that I can handle loading, transport, and setup and take down by myself; and that I do not need purpose built buldings etc to store the beast. It's also preferable that I don't have to buy another vehicle or switch to a van if I can help it, which means a scope that can be broken down to fit in my 4WD and campertrailer in component form. I also want to avoid falling off ladders, which has recently happened to a friend in Canada.
For those reasons I have decided to draw the line at anything over 22" in a fast f Ultra Compact form factor. The Obsession 22" UC size is the boundary for me.
I am very interested in the Hubble 20" Ultra Light as it ticks all the boxes. It's shown here:

Have to wonder if it's a coincidence that Hubble is using the same website colour scheme, font, and layout as Obsession; and have moved in on David Kreige's Ultra Compact product range. Ain't Competition Grand.
Hubble's 18" introductory pricing is placing it just above GSO's 16" Stut Dob which sells really well here.
