mw, ours are very, very light and no anti-slip at the bottom. I just looked up what you were referring to, and it appears those are the ones we're using. They're yellow and so very light.

I used to use the yellow SpeedEzels all the time. Use drafting tape, or even masking tape. A small piece on each end and the easel will stay put. This is not rocket science.

And yes, good 4 bladed easels can be more expensive than enlargers, especially the big ones. Adjustable means just that - you can adjust the size of the image. (unlike the SpeedEzels)

BTW, when bought new, the Ganz easels had little foam or rubber feet that could be stuck on the bottom. They never worked well, and eventually fell off ...
