There are a lot of them . . . and a lot who are not. Caveat emptor. You can try Apple Stores and Mac vendors who often have computers they are trying to unload. Otherwise, I suggest finding a "Local" dealer so you can see and inspect the product. You can also make sure that if something goes wrong, you can find the guy! Like . . . if it turns out to be stolen! Or if you find out that something is not working or wrong you are not trying to mail back a computer and all of that crapolla!
You also want to make sure it comes with legitimate Installation Disks. Too many people come HERE with a problem that would have been solved if they did not post, "I have no idea where my disks are," or "it did not come with them!"
I have a local dealer, and if you PM me I will give you his contact information. He is probably not local to you.

His secrets are not sold cheaply.
It is perilous to waste his time.
