What happens when this unit breaks down? Do you ship it back or will the warranty be honored at a repair shop, and will the shop honor the warranty? Probably not, since you ordered from a sell all store. Why not buy from someone with a proven track record, and can also answer questions that you may have. This way you will get the machine you want or need with all of the other things that fit your machine.
