According to Pinside there is 60 premium/Le owners combined. I’m not sure they made the full 500 LEs they intended to. I can’t imagine sales outside of the US beyond a handful or so.
Quoted from kst8cat:There are a lot fewer premiums of this title than there are LEs. The premium is the hardest to find. I had a chance to buy a NIB premium for $5500 in 2015 back when distributors could mark them down below MSRP. But I went with the pro because I didn't think the premium/LE offered that much more in the way of extra features.
