Sewing machine dealers - oh my!! Almost as bad as used car dealers. They will take a look at you and try to sell you what they think you can afford. They will try to sell what they need to push in any given month. (I wanted to look at the Horizon but they poo-pooed it saying "you dont' want that - it has had mother board problems") and then steered me to a Viking 875. The next month, still looking, they steered me to the Horizon.
Figure out what you want and then go shopping for machines that have the features you want. Trust other owners for the issues they've had rather than listening to the dealers.
Good luck and try to have fun with the search.
