if you're not careful, you could easily move that easel out of place.
I am totally ham fisted and even I don't move the easel out of place.

Can't you just try being careful.
If not you can find 11x14 Saunders 4 blade easels for $30-40, I recently sold a ugly but fully functional one for about $6. These are good easels, They have weight and a rubber bottom so they are not easy to move.
