I upgraded all of my equipment (except for speakers) over the last year and the toughest thing to find was a well made stand/cabinet. After months of searching stores and on-line I stumbled across a company who makes cabinets that I consider to be one of the best values of all the upgrading I did. Not inexpensive, much a much higher quality than those "brand names" you see advertised in the a/v magazines. Not sure if they have a model that fits your needs but take a look. 100% hardwoods, no chip board or veneers. Come to you completely assembled like a quality piece of furniture. Take a look at: (standoutdesigns.com). I'm not associated with this company in any way except as a very satisfied cutomer.
Salamander Quality
I'm looking at the Salamander Synergy twin 40, but can't find much as far as reviews on it. I'm mainly looking toward the twin 40 for the design. Mobility is important & the twin 40 can be had with the saturn casters. Quality...as far as fit & finish are my concerns with the salamander. Before a plop down $1500, I want to be making the right choice
