Speaking of Ikea. I stared with an Ikea hack as my standing desk. Building a combo coffee table with a book shelf as a keyboard tray, all for about $34. That sat on top of my existing Ikea desk/table. I used that until I was convinced I wanted to stay with the standing desk.
There are two drawback to the Ikea hack solution. 1) they are not readily adjustable. You don't want to stand 100% of the time, certainly not when starting out. 2) they can be very top heavy if you have more than one monitor and a workstation AND a laptop.
The electric motors look cool, but are totally unnecessary. It takes about 10 seconds to crank the table up or down by hand.
What goes unmentioned in most standing desk articles is the need for a really good mat to stand on. Here are the best I've found that are also a reasonable price:
