Chief Mini RPA Elite mount custom or universal
I'm looking for a ceiling mount for Sony VPL-HW40ES.
I have decided to get a Chief Mini RPA Elite mount.
The price of the custom bracket one is not much more expensive than the universal one but need to special order. It'll take longer to deliver and no refund or exchange.
Is the universal bracket good enough?
Is the custom bracket worth the extra cost and trouble?
Bonus question, is it alright to screw the mount directly to the ceiling without ceiling plate and extension column?
