God I fucking hate plaster. Granted, my house uses oldish-fashioned metal lath and plaster, but it's such a ball ache. I wish it had been built with just drywall so I could use stud finders and shitty drywall anchors. Instead it's all fuckass toggle bolts and "use this giant magnet to find the stupid screw that attaches the stupid lath to the stupid stud." Ugh.

I have a relative that had these, he recently upgraded to drywall so he could easily make modifications.
