I work at a LQS and I also use to work for a sewing machine dealer. If the machine has the same model number it is the same machine at either store. But most dealers do not sell the cheaper models that the chain stores sell. The machines are just not that good a quality and a dealer stands on her (his) reputation. Most dealers wont honor a chain stores warrenty even if it is the same make and model as they sell. You would have to have it shipped back to the manufacturer at your expense, because they did not make the profit on the machine to start with. Hope this is a help. :|
