Contemplating Coffee Tables

In the last week, I've decided that I need to make a few revisions 'round this apartment. Perhaps it comes with the territory of the new year, but I'm planning some rearranging in the near future. Swapping things around won't exactly placate the need for some freshness and change though, so I know what I need to do:

2012 must-do #1:

Get a new coffee table, stat

Here's what I'm currently working with:

My mid-century table isn't terrible, and I like its height because we eat dinner at this table more often than not (just keepin' it real). Yet, I'm desperate need to banish some of the wood tones in the living room and would love to introduce some glass, some brass and/or some marble in its place.

The simplistic lines of Jenna Lyons' vintage Knoll coffee table as well as its substantial size are just what I'm looking for:

and I definitely want a table with sufficient surface area for displaying books, like Jordan Ferney's:

At this juncture I'm gathering inspiration and opinions; but if money were no object, I'd have a tough time deciding between these pretty (and pretty pricey) options:

(Harvey Probber travertine coffee table via 1st Dibs, $3,800)

(Origami coffee table via Anthropologie, $1,300)

(French brass hoof cocktail table via 1st Dibs, $4,450)

(Two-tier coffee table via 1st Dibs, $1,980)

(Two-tier brass coffee table via Ebay, $595)

Ideal characteristics of my new coffee table:
--glass
--brass
--marble
--sizeable

Do you have any great options that meet this criteria?
