When it comes to BD, there are an army of trolls lurking in the wings.
I bought my Motobecane almost two years ago. Built it up with a build kit from Colorado Cyclist, all Dura Ace with Mavic Kysrium wheels. Comes in at 16.5 lbs. I've changed the seat to a Flite and the seatpost to Thompson. Way more comfortable now. That Douglas seat was about as uncomfortable as a seat can be.
Here's a pic I took for another thread. Sounds like you are getting a great deal. My experience so far says go for it.
