Hi there.
I am a videographer who is retiring. I have a 5 foot Kessler slider with the Elektradrive cineslider for programmed motorized slides and also the motorized pan and tilt head. Two control devices and battery. I also have the heavy Kessler tripod head that is needed to stabilize the long slider if it is on a tripod. I also have the tripod and spreader I use for this. The kit includes the case for the cinedrive, etc. and the fabric case for the slider.
If you are a filmmaker considering this, you ought to check it out. I don't expect or want you to make a decision for this without first testing it. I am in Manhattan Beach, Brooklyn near Kingsborough Community College.
I'll post the photos I have, but with so much stuff, I may not get it all.
Here are links for some videos where I used the slider:
