I bought a sit-stand frame from Ergotron[0] which I fitted my old desk surface onto which saved me quite a bit of money.<p>I don&#x27;t like cranks or electronic motors. My criteria for a sit&#x2F;stand desk was that it must be fast and practically effortless to switch between the two positions. For that you cannot beat a lift-system like the one in the Ergotron.<p>[0] <a href="http:&#x2F;&#x2F;www.ergotron.com&#x2F;ProductsDetails&#x2F;tabid&#x2F;65&#x2F;PRDID&#x2F;757&#x2F;language&#x2F;en-US&#x2F;Default.aspx" rel="nofollow">http:&#x2F;&#x2F;www.ergotron.com&#x2F;ProductsDetails&#x2F;tabid&#x2F;65&#x2F;PRDID&#x2F;757&#x2F;l...</a>
