Yeah I took a eggy paddle and heated up the prongs with a lighter and bent them upward so they didn't pass over the feedneck hole. Works wonders. After seeing people doing this JMJ started selling paddles like this.
There's also the JT Tripod system, where its a 200rnd shake and shoot with a removable motor/board and battery housing.
And you can't forget the shredder 3000 ( think it was 3000) which was a 18volt 300round monster revy, always wanted one of those.
