Anyone with an XL on a remote pan and tilt head?
 

We're planning on buying a couple of XL H1's for multi-camera work and plan on putting one on a remote pan and tilt head while using the Console option to control the zoom and focus. Since Lauri mentioned in Shannon's "Console" thread that he would be using his H1 on a crane, I was wondering whether he, or anyone else, has experience with different remote pan and tilt heads. My on-line research has led me to the Varizoom VZ CS1LK (only $4K, but no presets), the ESI Model 180, and the Telemetrics PT-CP-S2, but I have no experience, nor can I find any reviews, of any of them.
If anyone has personal experience or can direct me to another on-line forum that discusses such issues it would be much appreciated.
