I would go with a new machine every time no matter how good the deal seems to be. You have your guarantee if it breaks and if you decide you don't like it you can return it most of the time. if you get that good deal it's buyer beware. You could be buying someone else's problem.
When you're dead you don't know you're dead. It's the same way when you're stupid.
