BuyDig via eBay offers the Segway MiniPro Smart Self Balancing Personal Transporter in White for $599 with free shipping. (Segway Distribution via Amazon charges the same; Sam's Club charges the same for Sam's Club members.) That's tied with our mention from the week of Black Friday as the best deal we've seen. (It's a current low by $8, although most stores charge around $600.) It features top speeds of 10mph and distance of 14 miles on a full charge.
