A scooter for 4 yr old nephew....?

I want to get my nephew a scooter for his birthday. He will be 4 yrs old:) I want to stay with a 3-wheel scooter, but I want something he can use for a couple summers. He is REALLY tall for his age so I hesitate to buy a "pre-school" scooter. If I were to buy him a 2-wheel scooter, is there such a thing as "scooter training wheels????"
OH, and my actual question:) As parents, what has been your experience? Who makes the best scooters? I also want to stay within a reasonable price range, especially if I am going to purchase a 3-wheel scooter.

Oh sorry...I want foot (pedal?) power:)

are you asking about pedal power or engine powered?

either way for more use i would go with the 2 wheeler

they make adjustable training wheels, so take it from there
hope that helps you out

pedal power, may sound corny or u may really like it depending on where you are from, but how about a tractor
they are 3 wheels 1 front 2 rear and most kids love them

Buy him the one that most comforts and just get him in the training of riding the scooter

get a (ultra light scooter) they are a realy great quality scooter and they are cheap
