The Eurostar or Banbi are 2 other a/c than can be a microlight or a SEP, but no need to limit your selection to a/c that can fall into both microlight and SEP categories. Loads of SEP only kit aircraft available, check the PFA website for suggestions.
(I'd recommend a
Pioneer 300 - 130KTS @ 16trsL/Hr, wobbly prop, retractible gear etc
)
