I know I want a Brother CS6000i sewing machine. I've looked at them online and at the WalMart that is in my town. The closest dealer that sells Brother sewing machines is 4 hours driving time away from me. I've read that Brother makes low-quality machines for chain stores to sell. I bought my last Brother from WalMart,but that was 15 years ago. Would I be making a mistake buying my new one the same way this time?
