Don't know if there's already been a post about these...
but SkyWatcher has released a new range of collapsible auto-tracking dobs.

Pretty interesting, particularly for folks who like their dobs and would like the hassle of tracking taken care of...without buying an after-market base.
I'd be keen to have a look at the 12"... which will apparently be available soon.
