Well, the only ones I know are the chinese ones, from Aliexpress.
I bought a couple out of curiosity. They're fine, but they seem a bit fragile / bad designed.
I've seem some pictures of the INL ones and they seem to be a lot nicer than the pirates I got from China.
I know there are other people selling repros around, but I can't say at least how good they "seem" to be because I didn't see the "guts" of the product, not even in pictures.
Basically, I'm doing my own repros to myself.
It's a process that I've learned and am still learning a lot!
Also, it's a nice way of relief stress.
