My daughter got this for her sixth birthday in 2010 and loved it, but the Jessie got lost. After months of searching without any succcess I went to replace the doll but had to get the full set again, and was astonished to see that the price had trebled since the original purchase. My daughter had really loved these interactive dolls so I bought them again. She gets great entertainment from them and plays with them with her younger sister alot.
They are a great toy, with a good 'strong' female character, but I'm not sure they are worth the 2011 price - unless you've got a broken-hearted six year old!
