... and some of those types score quite high in the accident statistics.
A bit of clarification/opinion:
* ULM is defined by EASA as being MTOW 450/472.5 kg, though that seems to be on the move now; the exact rules being left to individual countries. LSA OTOH is 600 kg MTOW, in all EASA-land.
* a 450 kg two-seater will only seat two - of average build - if no luggage is carried, and minimal fuel. With only the pilot on board, they're ok.
* the types you mention have been engineered to get the maximum out of the legal limits, which makes them demanding on pilots.
* be aware that some countries impose limitations on foreigh-registered ultralights - as does my own, to my eternal embarassment
Allow me to suggest you should better define your "mission profile". I understand you wish to travel, but
* one person, or two, or more than 2?
* can you live with the day-only and/or VFR-only limitation?
All that said, take a look at the Europa, you might like it. But be aware that it is sold as a kit, and assembling one is not everybody's job. And they're rarely offered second hand, guess why?
