$25  Brother sewing machine. It works beautifully; I just upgraded a few years ago and no longer need it. Perfect for the young or novice sewist. If your young one has been asking for a sewing machine, but you've been reluctant to invest, this is your answer.  You can't buy a toy machine for this price.

$30 Singer serger. Perfect Finish.  I bought this a few years ago and left it in the box. When I tried to use it last year, I found threading it too  challenging. For someone who knows sergers or has the patience to learn it, this is for you.
