I'm not tempted after looking over the specs. The Vitesse D3 (mine was $500 new) weighs the same or less, can also fit into an airline legal suitcase, but offers a faster and more stable ride, more upgrade/customization options, can transport more luggage, and can fit someone 6'4'' tall. The only advantage the Curl/Brompton design offers, the smaller fold, would not be enough to offset all these disadvantages to me, since the Vitesse frame also folds small enough to carry onto buses and trains, although it does take up a little more space.
