I didn't read this thread, but based on the first post, she clearly sucks at riding and improving isn't a priority, so what she gets really doesn't matter. Pickup a copy of the TW Snowboarding Gear Guide from a couple months ago and have her flip through it. She can then pick the board she likes based on graphic/name. Then you pull out your wallet, buy it, and it's done.
