One of the newest SLSA is an all-American design, from Arion Aircraft and it’s called the Lightning LS-1. Winning its approval just before Sun ‘n Fun 2009, LS-1 was preceded by some 80 kit Lightnings the company has sold in the last three years; more than 40 are already flying. I found the Lightning great fun. You might, too.
CORRECTION: In this video, I refer to a “retractable” version of the Lightning in kit-built aircraft form, however, that is an error. The model was never designed with such equipment
