I am doing some planning for a project, I am looking for a manual adjustable height desk. I found this http://www.tablelegworld.com/Motorized-Table-Legs/Manual-Adjustable-Crank-Frames/200-lbs-with-gear-shaft/Manual-Adjustable-Table-Frame-Height-Range-22-to-31-1-2-BLACK?gclid=CK6Cybv5w8ECFcsJwwodsnMA6A&#.VEmU__lr6nB I am wondering, has anybody heard of this company. I am trying to find out if they sell a quality product. It seems like a good deal (compared to everything else $500-$600).
