I got them for cheaper than Rogue Calibrated Steel plates and they are super precise at only +/- 10 grams deviation. I purchased them off of someone who imported them and then changed their mind and went a different direction, hence a much better price for me. Luis he drive from another state to deliver them to my basement. Couldn’t refuse that deal. I picked up the change plates from the UK distributor of ATX. The importation duties and taxes are what makes these plate currently unreasonable here.
But if you are in the UK, or EU or AUS, where there are ATX dealers (ATX is like Rogue in Europe) they are very reasonably priced.
Several companies are now offering this same type of plate like Kensui. So until ATX is officially here distributing in the USA, look elsewhere.
