Whatever you do, don't buy any of the made in China crap. The US needs to put a cap on importing that garbage and make it all illegal. Many don't work right out of the crate and most don't last 500 miles. Same goes for all the made in China Enduro dirtbikes, go karts and ATVs.
Honda and Yamaha scooters are expensive but you can buy used ones all day long for about the same price as a new POS Chinese scooter. The little 50cc Jap scoots can go 20,000 miles without issues and parts/service are as close as your local dealer.
If you're talking about the skateboard style pictured above I think they're all pretty much disposable. Tons of recalls though on various models though...if electric I wouldn't charge it inside the house or in an attached garage.
