ELAC B51 vs Sunflower Redux

what would you get and why? 

i have an existential cliff hangar here...
the B51 will be about $2000 when it is released summer 2018. the sunflower redux i can whip up with about $600 dollars of parts and cabinet labor...
my room is about 8 fett wide by 30 feet long by 8 feet high
I need to fly in anything I get.. either the ELAC in luggage or the Sunflower parts...
