I bought that same one used on ebay for $18.
Some side notes: the MyQ compatibility tool is poop. I have a chamberlain garage door opener. So naturally I try the tool and it says I have to their new product for $$$$. My garage being about 5 years old, I remember, was sold with a different hub than the one shown in the compatibility tool. MyQ doesn't sell the old hubs anymore so they won't tell you what your garage really compatible with. They will only show compatibility with their current products. Thanks MyQ.
I look up that older hub. It was super expensive but sold on Amazon. I read through the comments. The Chamberlain MyQ hub won't work anymore even though it is being sold on Amazon. Weird. But when you call to complain, they send you the Liftmaster hub shown in @mik3 's post. Even though it is a Liftmaster, it will work with Chamberlain. Odd!
MyQ is so weird.
