Check out the easel now being offered by David SORG. Although I have not yet used one, I can certainly speak to its design.
Many artists have never had the opportunity to play with a counter-weighted (as opposed to crank-type) easel, because even the largest art supply stores don't offer them on the floor, opting instead for a range of what (to me) are very highly-priced and widely distributed easels - many of which are
well over $1000.
Several years ago I had a custom easel designed and built. It, too is counterweighted.
Moving the tray is truly a one-finger effort. Moreover, because the mechanism is in the center, you don't run into the jamming that can occur in trays that require two mechanisms at the sides. Unfortunately the person who built my easel is no longer available.
I will need a second studio easel in 2005, and I'm so happy to see one that looks this good. It would be great to hear from any of you who have actually used the SORG easel.
There is an excellent article on the SORG site addressing things to consider when buying an easel.
And, no, I am not getting paid for this post
