Are you an experienced sewer?
Sometimes a complicated machine with "all the bells and whistles" is not the most practical/useful for many people.
Do you want to do machine embroidery?
In my opinion, it is difficult to find one machine that will do "everything" well.
Some of the members have a "big" machine that stays at home, and a "lesser" - lighter weight, fewer features, less expensive machine - for going to classes and retreats.
I also think there is no such thing as a "perfect" machine. In my world - "very adequate" is what works.
