Walmart machines:-
I have 2 Brother CS6000i machines, my daughter has one, and BFF has one. I have sewn on all of them and had no problems.
I also have the Brother 270D and have used it for embroidery and for sewing.
No problems with it either.
I bought my Singer serger at W-M too, and use it all the time, and never had a problem with it either.
I keep all these machines clean, and they work fine.
