Eve (MDEA) was quite an amazing experience, though (as always) lacking in a certain quality that MDA/MDMA have.
The ones that have similar action (though subjectively don't really come that close) are the aminoindane-class analogues. They're interesting in their own right, too.
MDAI is odd and not all that much fun (on its own at any rate), and AFAICT from reading various forums, 2-AI and NM-2-AI don't really seem to do much for people either.
It might be rare to know what you're getting, but that doesn't preclude you from utilizing various drug testing services that will test what you have and let you know the results.
IIRC there are others that have been found to have similar action but without the neurotoxicity. MBDB was one I think.
Personally I'd love to try EVE and EDEN too... but that's a pipedream in a world where it's rare you can ever know what you're getting.
