Buying a Telescope for My Son

I want to buy my son, who is turning six, a telescope for his birthday. I don't want to spend a fortune, but one site I looked at for advice said anything less than $300 is a piece of junk. Anyone have any advice (including specific models) on one I can by this budding astronomer for $100 or less?
