Note - This is not a complete survey.  More are likely to be added.  The pertinent features vary between various makes and models here.  The Avid, Just, Kitfox, Rans, Sky Ranger and X-Air all have folding wings which is very convenient for limited hangar space.  All, including the Just Highlander, are available with tricycle gear.  Engines are highly variable from small Lycoming and Continentals to Jabiru, Rotax 912s, Subaru and VW Revmaster.  Some, like the Kitfox, are available at reduced cost with the Rotax 582 and 503 2 stroke engines.

A number of these photos were obtained from ads at Barnstormers website and were/are for sale.  Like the Avid Mk4 in the first photo was listed for $23.5k.  It has since been sold.
