What are the electronic vehicles that you can stand on for moving from place to place?

Hey people at Yahoo. I need your help. I am fixing to go on vacation and I am disabled. One of my disabilities is that I can’t walk very far without being in great pain. I don’t want to get a sit down scooter or an electronic skateboard with a handle(for lack of a better discription). I have seen this thing you stand on with your feet side by side that you can just step up on and ride from place to place and then step back off of. I have searched the internet and can not find them anywhere and I think it is because I do not know the name of the item I am looking for. Can you guys help me out and if you know of anything that sounds like what I just described, give me the name so I can look it up. I am trying to find one to see if I can afford to get one before I go on my vacation. Thanks in advance for any help I may receive from any of you out their answering questions for Yahoo!!!!!!
