I've purchased 4 of them through dealers on GunBroker in the last month. You can still find them at good prices if you check late at night, early morning and especially early on Sundays. There is one "buy it now" MOE version available for $599 as of 8:50AM. Search for 811034 and you will find it. If you want a non MOE version search for 811033. If the dealer is selling it with a high capacity (25 round) magazine have it shipped to a dealer in PA or ask them to swap the mag -- most will work with you.
Looks like it just sold (9:30AM).....
You can still find the 811033 Threaded Barrel non MOE Model for about $499 and the 811034 MOE Model for about $600. The biggest pain will be ammo and mags at this point.....
