I am really close to getting the XR-18. But this is *exactly* what is stopping me!
If the X-Touch is the way to go with the XR-18, why wouldn't I just start off with the X32 Producer for about the same money, and have even more control with the added convenience of a single rack-mounted unit???
As a musician, I have learned to never but new. Even with the XR-18 and the X-Touch, I am still half the cost of the Producer.
As far as the X32 rack? You are getting the same number of channels as you get with the XR-18 until you add the digital snake.
As far as being able to pack up and travel? The XR-18/Xtouch is easier to transport.
As a reference, here's the back panel of the X32 rack...
