My Poor Desk

For those of you who have never visited my home, I have a tiny desk on wheels on one side of my living room. H has the whole office to himself, and I work near the TV so I can do reviews and stuff. JoJo loves climbing all over the desk almost as much as he loves jumping off of it. But see, it's a cheap piece of crap. I've already bought it twice because the first one had a part snap off after 3 years. This one is about to bite the dust too, and I don't know what to do about it. Spending $70 on a new one would suck. But I can't keep Jojo away from it, so soon I won't have a choice. I'd rather spend twice that on one that won't need replacing in a few years.

I'm totally open to suggestions for any other movable desk that has a pull-out keyboard tray, and at least one shelf that won't be taken up by the monitor. This is what I'm using now.

Little help?
