You really can't beat the Creator series. For $20, the Propeller Adventures set gives you three models in one set, which you can build from the same pieces. A two-engine plane that transforms into a jet that transforms into a hovercraft—plus an extra model instruction booklet that you can download from Lego's site.

But their true value is not only that. It's how much you can learn from building them and then creating your own models. [Amazon and Lego]
