I agree with Jim 5. I am looking for a scooter right now, and there are some great deals to be had. On Craig's list I am finding two great models, the Yamaha Vino in 50cc and 125cc, along with models like the Honda Ruckus, and others for quite a savings off new.
Personally, I would stick with a Honda or Yamaha scooter as they have the scooter thing down. My edge would go to the Honda as my wife's grandpa has 2 Honda sprees and 2 Honda Helix scooters and they have been running for many years with the whole family riding them at events and such.
If I were you, I would really spend the extra money for a 125cc or up scooter. I've seen people around town with the 50cc and if you are at all a bigger guy, the motor on those seems to really strain to get up to speed. I know you have to get a motorcycle license, but it would be worth it long term.
Or, go with a motorcycle like a Honda Rebel, Kawasaki Eliminator 125, or the Suzuki's 200cc model. I know the Rebel gets about 66mpg.
I want a scooter, but now I am leaning toward a motorcycle. A good all around town and sometimes highway setup would be a 250cc smaller cycle.
The articles I read about Chinese scooters is that they can last awhile, but when something breaks it can be almost impossible to get replacement parts for them. The article said that the Kymco brand, (I think it is made in Taiwan) is a good bet as they make a large amount of scooters.
