New "E Pump" Compressor offered by Air Force Guns

Hey All,
Anyone else get the emails from AirForce advertising their new “E Pump 4500 compressor? $899. Any one have the opportunity to get one yet? Their site says they’re out of stock already, but perhaps they just haven’t received any from the maker as they are brand new at the 2018 Shot show.
I’d be interested to know if they are better than the Chinese products.
