I don't know how much you want to spend but I have a Salamander Synergy Twin 40 in Walnut w/ black posts, mesh doors, and walnut side panels and I'm about to add their Plasma mount option to mine. It's well built, configurable, good looking furniture but it's not cheap (inexpensive). They also make a center channel speaker shelf and have many different heights (20,30,40) as well as widths (single, twin, triple). My rack with all the options except the plasma mount was about $1500, the mount is $399. They also have some cool looking polished feet that I didn't get before b/c I had a 300lb TV (plus over 100lbs of other electronics) on the stand previously and the optional feet were not guaranteed to hold the weight I was carrying in the stand at that time. Now that I'm using a 60lb LCD I could get cool feet.
www.mander.com is the URL. I believe AudioAdvisor.com carries Salamander and they are an excellent company to do business with BUT they don't carry all the finishes and configurations so I purchased mine locally and saved the expense of shipping 200lbs of large boxes.
