Hi Folks,

New to CNC but I have been reading and watching a lot. I am converting an X3 Mill using LinuxCNC + Mesa 6i25 + 7i76 and I am looking to buy a VistaCNC P4-S pendant but I not sure if I should get the P4-S ($269.00) in which the E-Stop is via USB and LinuxCNC or the P4-SE + iMach EE Box ($317.00) which is a hardware E-Stop solution. There is a $48.00 difference between these solutions. I'm not try to be cheap but going for the extra is starting to add up and I don't want to spend extra and have the cheaper option be the better option.

Thanks
John.
