Get her something cheap like a Duncan Butterfly. You can pick one up at a grocery store for $3.
Young kids bounce from fascination to fascination, get her learning the basics and then go from there. I let my son play with an old Imperial that I had in the house and had him doing super basic tricks before we moved up to his current yo-yo, the YYJ Classic. He was happy at first just learning how to make the yo-yo go up and down.
