Powerline Seated Calf Raise PSC43X

Hey, I've been looking for a calf machine actually (even though my name is LegDayEveryDay, I train mostly my hamstrings and quads, although my calves are quite large, they're lacking behind as I don't train them directly). I noticed another calf machine that sells for $2000 sold by Gray Fox Canada, however this one surprisingly is a lot less. I have a few questions about it: * Does it support standard olympic weights? (Two inch holes- Weights used in most commercial gyms) * How much weight can it hold in total? (each pole)
