I was thinking, "why not just buy a standing desk?" But then I saw the prices :-). Well, if you have the right tools, you can build quite a great adjustable desk, but you'll need more than IKEA. Off the top of my head, here's some things that you could use to build a manual or electric adjustable standing/sitting desk:<p>Metal tube - <a href="http://www.metalsdepot.com/products/alum2.phtml?page=tube&LimAcc=%20&aident=" rel="nofollow">http://www.metalsdepot.com/products/alum2.phtml?page=tube...</a> ;<p>Threaded rods - <a href="http://www.ebay.com/itm/3-4-6-x-3-ft-ACME-Threaded-Rod-General-Purpose-Class-2G-/220993986391?pt=LH_DefaultDomain_0&hash=item3374449f57" rel="nofollow">http://www.ebay.com/itm/3-4-6-x-3-ft-ACME-Threaded-Rod-Gener...</a><p>Gas springs (several of them would hold the desk pretty firmly, and you can adjust by pushing it down, with some locking mechanism in place) - <a href="http://www.ebay.com/itm/Two-USA-Made-Liftgate-Lift-Supports-Shocks-Struts-Props-Gas-Springs-4857-4856-/130740629417?pt=Motors_Car_Truck_Parts_Accessories&hash=item1e70bfafa9&vxp=mtr" rel="nofollow">http://www.ebay.com/itm/Two-USA-Made-Liftgate-Lift-Supports-...</a><p>Reduction motors - <a href="http://www.ebay.com/sch/i.html?_trksid=p5197.m570.l1313&_nkw=reduction+motor&_sacat=0" rel="nofollow">http://www.ebay.com/sch/i.html?_trksid=p5197.m570.l1313&...</a><p>OR steppers (if you go all out) - <a href="http://www.ebay.com/sch/i.html?_nkw=stepper+motor&_sacat=0&_odkw=12v+motor+gear&_osacat=0" rel="nofollow">http://www.ebay.com/sch/i.html?_nkw=stepper+motor&_sacat...</a><p>I guess the work involved is not for everyone, but it could be a fun project :-)...
