1x Used THK KR26 industrial rail with approximately 130mm effective travel distance out of 200mm total and 2mm pitch. Powered by 0.9 degree motor.

This is a good configuration for a studio setup with Windows PC operation.
1x (older model) BLE controller with BLE USB Dongle
1 USB Stick with MJKZZ Stackrail V2 program for Win 64 PC and instructions (Also available for download)

1x 12V USB Portable Power Supply and power cable
1x Canon Camera trigger cable
1x New Arca Swiss camera quick release system
This system appears closer to the Ultra rail package for $406 with the exception that there is a 130mm travel range rather than the 70mm travel range, and the controller is an older version with BT connectivity.
Tested on a Windows PC using GUI as shown in pics. Very smooth operation
