What's a good weighted electronic keyboard for my six year old's piano lessons?

Daughter (age six) perhaps to begin piano lessons. Considering a weighted response electronic keyboard as a piano substitute. Seeking advice in brands, models, retailers, price, durability, and indeed, overall wisdom of this route over standard piano. All views even slightly extraneous welcome. Thanks in advance.
