There's really no way to tell. They're probably all used boards. They may or may not have been tested. With iFIXIT boards you know it will work. It's up to you to determine which is the better bargain. If you have lots of time and patiences go for the cheap one. If you need to get your computer up and running, get a known good board with a warranty from iFixit. It's the old deal, you get what you pay for.
