One thing, the home telescope builder still, for the most part, follows the
Dobsonian way, my Babylon 8 which came to be with the help of many others is
a soild tube Dobsonian that has a bit of a mod so it's eayer to use for
Sidewalk Astronomy.
I know I've read of and seen home made truss scopes too, and as others have
said, I've never heard of the one you posted about. There's one small
company right here in Calif. I wish I could win the Lotto, as then I could
afford to have them make me a verson of their design to fit my B8's mirror,
it's a cross between closed tubes and truss, as it's a framework that has
two sections, one that slides into the other for transportaion. Hay they are
in the FAQ too. But until that day comes, I use my B8, it might not be as
good as it could be, but I was the only one to do the hands on work of
building it and it's the best I could do.

As far as the store bought scopes go, the soild tube Dobsonian still in the
number one type of scopes sold and can be found very easy.

Sometime in the late 1970's John Dobson invented a type of telescope. This
was driven by necessity, in that cheap materials were relied on the build
a
telescope that resembled a cannon and used large bearings of Teflon and
Formica.
