I tried one of those when I bought my sewing machine 2 years ago. It's astonishing what they can do, like embroidering little pictures all on their own, telling you when the lower thread is almost consumed(?) and threading the needle all by itself (and much more).

In the end I bought a model that has been around since the eighties (a Pfaff Select) because I want it to last and honestly, most of the time I just need the most basic stiches, not fancy embroideries. The lcd-machines have the reputation to be unreliable, and of course they are very expensive too.
