The Potomac Mills IKEA is about 25 minutes from my office with no traffic. Assembly time was about 20 minutes. Total cost of acquisition and implementation finished up at $45.97 and 90 minutes of my time.
Here’s the table: http://www.ikea.com/us/en/catalog/products/10104295/#/10104295
You’ll need 2 brackets: http://www.ikea.com/us/en/catalog/products/00167472/#/76696009
And the shelf: http://www.ikea.com/us/en/catalog/products/20025047/#/20025047 (Which I didn’t secure to the brackets in case I have to move things.)
And if you don’t have any of your own screws, this will come in handy: http://www.ikea.com/us/en/catalog/products/70224228/
For my height, leaving the brackets at the bottom of the table legs put the shelf at the perfect height for my arms. Each bracket is secured to its respective table leg with two (2) 5/32 x 1 3/4″ screws.
Finally, in case you forgot where this journey began…
