Id reccmmend you give Multibox a try.

It was a great starup product for me, pretty easy install.

I started with 2 boxes and 3 macros.

One to accept the group invites, One to heal my main character and one to heal the following character.

I only use 3 keys for that.

Now I run 3 machines and got myself the vetra multiplexer, as it is a bit more stable than multibox.
