Maybe we are the odd ones out, but my daughter (10) doesn't have either. She loves to bake, though. But she does it in MY oven! It is "tradition" that when my parents come to visit, my daughter makes muffins for breakfast. At first, I helped her, or my husband did, or my mom. Now, she does it all on her own. She also likes to make pies and cakes and cookies. We typically have a potluck about once a month at church, and she loves to scour recipe books for something new to make for it.
I had a "hand me down" easy bake oven as a child, and really never was that into it. Where do all you ladies' girls use these things? Do they set them on the kitchen counter?
Sorry, I know that is not really what you were after, here... lol.
If she specifically requested an EBOven, then I would go for the "Ultimate" one, unless there is a prohibitive cost factor.
