In 2003, I bought 2 "new" Kenmore machines from a company in WA. The were discontinued and got really great deals on them. They came in the original boxes with everything included. they safely arrived in the mail and the girls have had no problems with them and they work great. In 2009, I purchased 2 sergers, that were used, and they were packed great with foam cut to fit the boxes, they run great, they also arrived safe and have had no problems with them.
I do alot of investigating with the person, with whom I received stuff before I commit to buy. I've had no problems and have been very pleased.
