My favorite is Bother. I tell people inteested in a new machine to go to the dealers and try them out. Dealers have support, instruction and repair. Most of the do trade in too. Check out the ones that have been traded in, the mark up on sewing machines is substantial and you can get more machine for the money if you take one that way. Usually the tech has gone through them and makes sure the work well.
Good luck in your search.
