I may have overlooked a few, but if one were looking for a kit that:

1) is light sport compliant,
2) is low wing,
3) uses tricycle gear,
4) is of metal construction,
5) built using primarily pop type rivets,
6) and has a bubble canopy,

then up until relatively recently, the Zenith Zodiac XL [1] appeared to me
to be the only choice. But the Rans Aircraft S-19 [2] kit has become
available. And Van's Aircraft is developing the RV-12 [3]. (I'm not sure
that the Sport Aircraft Works SportCruiser[4] is available as a kit, or
what type of rivets are used, otherwise I'd have included them.)

As far as I can tell, the laws of physics, legal requirements, and consumer
preferences seems to have lead three of the longer lasting homebuilt kit
plane companies to design relatively comparable planes (as these things
go).

Are there any other kit aircraft that I overlooked that match those 6
points?
