My recommendation would be to buy Pam's New Workout and see if you can get away with using the Euclidean features on it. If you find that you MUST have real-time performance controls then purchase EC V2 later. A great strategy is to not purchase your entire system at once but just enough to get you going. Then add modules as you gain more experience and literal hands-on knowledge of your system.
I will definitely research them and add the to the list of considerations.
I'm highlighting this... because doing your own research, reading the manuals (before buying) will really help you select the best modules for your needs.

completely agree with @Ronin1973 on these points - there really is no substitute for reading manuals as well as watching demo videos before buying modules

Utility modules are the dull polish that makes the shiny modules actually shine!!!
