The little ikea one is pretty good. Chloe has it in her room and it’s straight forward, cheap and cheerful and to be fair even my machine would have struggled with the couple of things she’s thrown at it that gave it the collywobbles:)
As for books, I’d be inclined to buy a nice binder and print a ton of kid friendly patterns from t’internet, use pinterest as a starting point and print off things that fit with what she’s already into. She could group the patterns together by size so that if yiur friends daughter has a meter to play with she can scour those patterns, then the fat quarters, right down to using little scrappy bits for mixed media patches, badges, embellishments for clothes, making cards/toppers for friends etc and jewellery.
I hope she has fun with her first machine
