I recommend waiting for Sam at CNC4XR7 to publish his update. I use his screenset on a 10 tool carousel ATC with Mach 3 on my G0704 mill, and its been perfect. Very reliable, and he's even customized it to my specific needs. During the initial configuration, I had some questions, and Sam called me to walk me through things. This was a huge plus in my book. Setting up an ATC in Mach 3 is not a trivial task, so knowing that your screenset comes with solid customer support is worth a 3 week wait for an improved screenset. Good luck with your project. You won't be disappointed if you work with Sam.
Here's a link to a quick video of Sam's screenset controlling my ATC.
