Hi!
You did not include your height and weight?
Thirty (30) mph is a farm town? If you are going 10 30 miles per day I wouldn't limit my self to 30 mph or a 50cc scooter. Best value in my biased opinion would be at least a 125cc scoot. Kymco is probably the best value.
All modern scooters are twist and go - no shifting - most meet CA CARB standards.
I just sold my Honda 600cc Silverwing scooter - too heavy and my Kymco People 150cc - too slow and purchased a "new" left over Kymco People S250 which is just right.
Of course I am 6'1" - 230lbs
