Mel, if you already have the Interactive Wall-E, it's the same size plus the whizbangery of lights and sound. Except it doesn't transform. It's cheapest at Big W at $28.88.

I got Transforming Eve and that was a huge dissapointment. The arms have very little articulation and besides the opening chest, minimal "conversion," 6 different eyes and its size. I would reccomend you stick to Interactive Eve, so at least your Electronic Wall-E has something to interact with besides you.

I did pick up deluxe M-O at Target's sale price. So cute. Much like you I love my robots too.
