I bought 4x25 pound plates on the secondary market for just over a buck a pound. I am not a competitive powerlifter. Calibrated plates are harder to handle than deep dish plates, but they look amazing. Accuracy is spot on, but that is not a big deal for me. In the space for calibrated plates, they are a reasonable value, but you have to ask yourself if you really need calibrated plates.
