I almost bought a Janome Hello Kitty one for my DD's 6th birthday (a year and a half ago). I decided to go with a cheaper machine. Boy did I make a huge mistake. I just got a piece of junk that is hard to sew on.
If I had it to do over again, I'd put some more money with it and buy a "real" machine. I may do that for Christmas because, although this little junky thing is light and runs off of batteries or electric, it doesn't perform well.
