What the thread found

• Preston systems are widely used by professional Steadicam operators in the US for features, television, and commercials
• The weight of the control unit (MDR) can be a limiting factor for Steadicam use, more so than the motor itself
• Smaller control units like the Arri SMC-1 are preferred for Steadicam applications due to their compact size
• The Chrosziel system with lightweight Heden motors or the CDM-100 motor offers a lighter alternative to traditional Preston setups
• The Chrosziel CDM-100 is described as intuitive and functions well with both modern and older difficult lenses
• The RT Motion MKIII is noted as one of the smallest motor driver options available and is compatible with gimbal systems

Depends on

• One rental house's experience with operator preferences may not represent the broader professional market
• Weight complaints may originate from gimbal operators rather than traditional Steadicam operators
• The RT Motion MKIII's quality and reliability were not verified by the person recommending it
• Discussion does not clarify whether Steadicam Jr. users have different weight requirements than full-size Steadicam operators
• Opinions on Preston systems being industry standard come from limited sources
