Your assumption has already really come to pass - my school's printer club is building >30 of them with a $250 price point. Assembly/labor cost should turn out to be trivial, add 25% handling cost, add another 25% profit margin, and you're still under $400 for a device that certainly rivals most $1000-5,000 commercial models. Such a cool machine: foolproof mechanism and folds up to ~8.5x11x4" but has the same build area as most RepRap Prusa Mendels.
