We definitely liked the cheerio type cereal made by Glutino better than the Perky-o's. I tried to feed the Perky-o's to our chickens and even they wouldn't eat them.

Envirokidz makes some great kid-friendly cereals They aren't exactly like the ones on your list, but I'd be surprised if your DD didn't like them. There really isn't a flake-type cereal that is like raisin bran. Probably the closest one I know if is the flaked cereals by Arrowhead Mills. They have one or 2 that are made without gluten ingredients. Health Valley makes a rice bran cracker that is the closest I have found to a graham cracker, but my kid's don't care for them that much. I have definitely had good luck with baking gluten-free "graham crackers", though.
Good luck, and keep asking questions. I know it seems overwhelming now, but in 6 months you are going to be an expert.
