Jag35 has released their motorized slider to help you perform smooth and consistent movements across your tracking shots. Starting at around $299, the new slider can be purchased with or without the motor, along with optional leveling legs. Considering what you could spend to get a motorized slider kit together from other manufacturers, the price is not out of the ball park. I'd like to find out more about it's fastest and slowest speed time across the 24" or 36" track.
