I'm in a college town. This means no superhighway riding needed to get to and from work (about 5 miles to work, big hills). I would love to just bicycle, but I get to work sweaty when I do so, and I have to look professional.
I bought a Chinese 50 cc scooter, rode the hell out of it for two years, then upgraded to a Chinese 150 cc scooter (google GY6 for the engine and scooter type). These 150 cc scooters are really impressive.
Mine was shipped from TX via some eBay reseller. My total cost was $1040 including shipping. It came in a giant crate on the back of a truck. It took me several hours to put it all together, check fluids, and so on--this was not serious mechanic work but I would not recommend it if you, for instance, have no idea how to swap out a light fixture or can't trade out a kitchen faucet.
For about $1000, I have a cycle that is quiet, fast (I've hit 65 MPH on level ground), ridiculously cheap, comfortable, has great storage under the seat and in a separate trunk, and gets over 80 mpg. It is very easy to service and seems bulletproof so far. I tell my friends that it's 80% as fun as a "real" motorcycle at 20% of the cost.
