Welcome to Geekhack!
Did the Massdrop Minivan come assembled, or have you got some soldering to do?
The cost is probably a bit higher than a mass-produced keyboard as you are getting a limited run custom keyboard with aluminium case. You could have settled for a QFR, or even a venerable Filco, but where's the fun in that?
Either way it should be a great keyboard and last you for years - just think of how many rubber dome keyboards you would have bought and discarded in that time. Ok, maybe not that many, but some anyway. And you wouldn't have enjoyed typing on them.
If you're worried about getting sucked too far down this little rabbit hole, glance at
this thread, it might help put thing into perspective a bit.
