Desks on top of desks never felt safe to me.

My recommendation (as it always is anytime these standing desk articles appear) is the Frederik from IKEA ( http://www.ikea.com/us/en/catalog/products/60111123/ ) Ok it's not $22 but I've picked up two now on special for less than $80.

I can assure you this setup is super stable. Even at this price, nothing wobbles. If you think about where the weight is in this setup vs. others. The only thing that shifts the balance from a 4 legged table is the keyboard shelf. If there wasn't a monitor on top of it, you might be able to push down hard on the shelf to tip the table, but I doubt it. With a monitor on a table, this thing doesn't move.

Put it on a solid desk and it isn't going anywhere. I'd bet that it's even more stable than the fredrik which has two skinny legs.

I have a fredrik [1], indeed it is a bit wobbly -- it's not bad enough to be a problem, it's a great setup, but definitely not the most stable.

This desk is awesome as a stand up desk. I also used it as a treadmill desk for 6 months.

Wow. Do you have a pic of that? My contact info is in my profile.

I had to do a little shimming of the shelf bracket, since the legs were not perfectly straight, but no wobbling here either.

I've been doing the "desk on a desk" setup for 4 years. I use double-sided tape to keep it in place at it works fine. And mine is a real cheap solution -- scrap wood from my basement.

I was afraid of this too, so I just bought an unfinished door from home depot (for $22 oddly enough), and some crappy filing cabinets from the local university that were the right height. Set door on filing cabinets => done. I could bolt the door to the filing cabinets if I really wanted to, but it's stable enough as is.

The other advantage of using a door is that they come in various sizes (both width and height), so you can get one that matches your workspace size. You can also stain them some cool color or buy some fancy wood grain if you're into that sort of thing.
