As John Rimmer, I got in touch with Amtech but had the same reply. I dont understand why you wouldnt have info on your machines you sell but oh well...... I also wanted a clean off with their machines against mine but they werent interested......... I dont need to see their machines work under there demo conditions, as I am sure you can appreciate I want to see any machine next to the one I am using else how will I know which one is better. So again if anyone has a CFR or Hot Fusion machine and I can see it working please let me know, best, Dave.
