Projector mount for JVC RS2200
I'm surprised at how difficult it is to find a good projector mount for a 50lb projector. In my research, I've found Chief, Dream Media adjustable mount, and Sanus but the information about them all is shabby at best. Is there a "go to" place for mounts? I want to ensure I am able to screw into a stud and many of these mounts appear to have 6-7inch bases meaning you'll be off center.. That sounds sinful for a $300-500 mount.
I have to be missing something here but I'm coming up very empty.. Help!
