Hoist makes a plate loaded leg press that is the best leg machine I have ever used. It is almost a cross between a leg press and a hack squat. It has the same problem that the leverage leg presses like Nautilus and Hammer Strength make though, is that it requires a ton of weight to get to be a challenge. I am by no means saying I am some beast of strength - my top free weight squat is like 315x8. But the Hoist and leverage machines take 10+ 45 plates for me to even begin approaching a working set weight.
