Found 2 bags. One of them looks like a near-exact ripoff of the Aer Fit. The Aer Duffel ripoff is a little different. Uses "waterproof polyester" instead of nylon and the shape of the shoe slot isn't as good-looking.

And of course, the quality will not be as good. In my experience, the zippers are one of the biggest places they cheap out on so you have to be careful opening and closing. And the stitching won't be as good either so you have to baby the product more. Also almost no warranty service whatsoever.

But hey, it's way cheaper. I'm going to sleep on it but I'll probably buy one of these bags to try it out and if I like it, buy the real thing.
