Where are you located? Ideally a local place that can support is always best, but otherwise I'm sure you can find a place that would ship to you.
eWheels is a pretty reputable seller, and I get a small kickback if you order through my affiliate link: www. ewheels. com/alien I bought a small inmotion scooter for my wife from them, and they have a small selection available.
Since I live in SF, I'm currently considering buying another scooter through Last Mile (lastmilesf.com). I'm not affiliated with them, but if you give them a call they might be able to ship it to you.
