Super affordable standing workstation built from IKEA parts - less than $50

I've been reading a lot about the health and productivity benefits of working at a standing desk for months now and today finally decided to head down to IKEA and grab the parts to build one. The inspiration came from an article about how to build a $22 IKEA standing desk. This seemed the most sensible way to go about getting what I wanted.

From IKEA

• (2) Lack side tables - $19.98
• (1) Ekby Viktor 11" shelf - $5.99
• (2) Ekby Valter shelf brackets - $8

From Home Depot

• (4) 5/16" x 3" hex bolts - $1.24
• (8) 1/4" washers - $0.88
• (4) 1/4" hex nuts - $0.24

The only difference from the article I read was that I used the bolts to attach the brackets since the table legs are hollow and I didn't attach the shelf to the brackets. Total was a touch over $60 with tax and gas to get there and back ($40 if you live close to an IKEA). I love this setup and the only thing I'm gonna change is to drop the bracket down about an inch and a half somehow to get the keyboard surface at a more comfortable level. I also found that I needed to put something about 1/4" thick under my keyboard to get it to be comfortable to type on; having the keyboard at an angle was hard on my wrists.
