The Europa springs immediately to mind... although that's probably because I've got a share in one.
Attaching/removing the wings is really a 2-person job with the standard equipment, but plenty of people have built enough "props" to enable it to be done by 1 person. It takes a few minutes. (The meaning of "a few" varies depending how often you get to practice it! It takes my group around 10 minutes, but we only do it a couple of times a year... it can be done far quicker with practice.)
There are plenty of others out there, too - I suspect most of them will be home-builts.
