What the thread found

• The Bartech Focus Device can accept motors from multiple manufacturers including Palomar Engineering, Heden, Stanton, Cinema Products, and SPF
• Palomar Engineering M-One motors are described as reliable and recommended options for the BFD
• Heden M26P motors work with the BFD without modification, while M28VP and M21VP models require a servo loop gain adjustment involving four resistor changes for optimal performance
• Stanton right-angle motors require a modification to the BFD to prevent motor damage and are noted to be noisy during operation
• Modifying the BFD for Stanton motor compatibility may reduce the ability to use other motor types as backups
• Cinema Products and SPF FMG-6 motors are mentioned as less desirable options for the BFD
• Motor selection should prioritize current availability, manufacturer support, and reliability over purchase price

Depends on

• The Stanton motor modification's specific impact on compatibility with other motors was not fully resolved in the discussion
• One user reports using a Stanton motor successfully, contrasting with others' concerns about noise and compatibility
• The discussion does not clarify whether the M28VPT motor (with T suffix) requires the same modification as M28VP
• Specific technical details about the servo loop gain modification and its reversibility were not exhaustively explained
