We got the Leapster Explorer for our 3 1/2 yr old son. A friend of mine with a son around the same age recommended it. Our son LOVES it. He only plays the Pet game that is on it and the Toy Story 3 game he got for Christmas. He does really good with it. I haven't tried the other, so I can't say which is better. I know the one we have connects to the computer and has other attachments and stuff for it that you can buy. It also has games on the computer and a way for the parents to track how their child is doing.
