Yes, both metal and hard plastic, prices range from around $30 up to over $100...
I just checked their app and the cheapest (in stock) is $89.97 for what appears to be what I'd call the standard size and a larger locking one for $119. If they have cheaper ones as mentioned above, they didn't show up in the app.
I only saw 2 different styles when I bought mine. It was around $27.
They do, the prices vary depending on the quality but I'd say anywhere between 30-60 bucks
