I would like to buy a sewing machine for my partner who is an intermediate sewer. I shortlisted the Janome DC3100 (electronic) and the 7025 (mechanical) but am unsure whether these are the best options. It was going to be a suprose present but then i decided to ask her and she is unsure which one she would prefer. It is going to be used for curtain making, dressmaking, clothes alternations etc.  Any advice re the better choice will be appreciated!
