Excellent easel. I just un boxed the one I had to buy for my college photo classes 10-12 years ago for use in my new darkroom. I always kept it in its original box when not being used and it still has a lifetime of use left in it. I think it was almost $200 new back at the turn of the century and I thought my instructor was nuts for making everyone buy one, but he was right in having us buy quality equipment.
I've never seen a bladed easel yet that kept "square". I've used the same cheapo Premier for 40 years--the one with the 8x10 on one side and the 3 smaller sizes on the other. Piece of junk, but at least it gives even borders. If I need bigger, I use my T-square, triangle, and light table to cut a mask out of offset printers' masking paper.

I have had good results with my Saunders. I suppose its possible they can get knocked out of whack but there are ruler marks on both sides of the masking blade to ensure one side does not get higher or lower then the other side.
It's a good easel. I owned and used the exact same model for decades. Mine started out square and it's still square. Still have it. Still gets used now and then for specialty purposes. No issues.
