any scooter or moped suggestions?

So here it goes. My commute to the train is short by most standards. I live less than 3 miles from my train station. I ride my bike to the train pretty often which I like but there is the reality that on some days doing so for me is impractical because I need to wear a suit, or I don’t want to be sweaty, etc.

I have been looking online at Craigslist.com primarily to pick up a scooter or moped. I hope to use it as the primary mode of train transportation and to run a few errands in town if necessary instead of using my car.

Quick details that may help form opinions. I am about 6″ 245lbs. I don’t expect to go further than into town and home, I don’t need the fastest wheels and I don’t want one with biggert than a 50cc engine.

I like the look of the Vespas but have no desire to spend 3-5K on this, I’d actually like to spend $1,000 or less. I seem to think the Honda Metro, Yamaha Zuma, seem to be reliable and some people seem a little off put by the Korean bikes (Kymco). Since I know buck nothing about all of this any thoughts you have would be cool.
