Coffee Table Roundups (selfishly personal)

I'm in the market for a coffee table (not just any old coffee table) to replace the one we currently have -- a wobbly piece of crap, whose lower shelf has repeatedly dropped to the ground sending magazines everywhere.
I'm looking for something either contemporary/Danish (1 and 2), clear (3) to open up the living room a bit, or straight-up modern (4).

I love the legs on 1 and 4.

The second, third, and fourth tables were either custom orders or unreasonably costly. The first, shamefully, is from Urban Outfitters. Ahhhh...life & death decisions...
