"Help me find a desk like this:
I like the legs. ...everytime I go on Craigslist I can't find anything."
To start, you probably won't find this exact desk on Craigslist. As the NY Times article (the source of the photo) says, it's custom - made from an old door (and set atop some nice sawhorse legs). That's the bad news. The good news is that you can easily re-create this look on your own with a little help from the local hardware store (that would be Cole Hardware for you) and some creativity.
In no particular order:
(A pair like these shown are only $4.49 at Ace Hardware)
Other "trestle" leg desks you might like, especially if you aren't feeling very D.I.Y-ish:
Braxton Table (from Target):
Madison Table (again, from Target):
Workstead Table (from Workstead - this is de-lux-e!)
Or you can source some interesting trestles from Ikea's Vika line and use some sanded/stained planks:
Hopefully this inspires you to keep your eyes open for a suitable slab of wood because if you find that, the rest is easy!
