I'm looking into getting my son a ride on toy for his 2nd birthday. I've been looking at the Radio Flyer Retro Rocket, the Radio Flyer Rolling Pony and the Ride on Excavator by Friendly Toys. Anyone know anything about these? I've read the reviews online, but just want a little more input -- in particular, is the Retro Rocket big enough for a tall 2 year old, and does the Ride on Excavator move well as a ride on?

Thanks!
