I would suggest the SQ 9000, in fact almost bought the only one left marked down at my local Walmart because I know friends with that model & they love it, I like the extra features. Since I didn't need it, just wanted it, I told a friend, she bought it.
I do have a low cost Walmart Brother, about 4 or 5 years old, I love it, great for travel & classes. It did need repair, I contacted Brother, they told me to take it to my local authorized Brother dealer for repair, that dealer fixed it quickly & cheerfully, no problems.
