Here's one guy's website describing his home built telescopes: http://www.roelblog.nl/category/zelfbouw/. Some of them are directly based on the Strock, the latest one, a 350mm f/4 is a bit more radical. The website is in Dutch.
One can hypothize that we Dutch have lots of time to build travel scopes, because of the generally bad weather, and the need to travel far away to be able to see DSO's.
