Hi guys! My name's Tony. I am planning to buy a Segway. Is an x2 SE a good choice?

Yes it is, nothing out their can compair to it.....That is the lates Segway street model.

Unless you plan on doing a lot of off-pavement riding, I would suggest an i2 instead for using around town. The i2 width is about the same as your shoulder width, so judging clearance is intuitive and more accurate. The x2 is wider, with greater chance of catching a wheel on something.
