I have a big one I bought from 'garagetoys.com'. it's been great so far. I'm happy with it. Mine has the narrow set of drawers on the right side. It's big, but well worth $1200. Try finding a similar quality unit for anywhere near that price.
Sam's Club had a similar one, without the right side drawers, for about $800, which I think is still a good deal for the quality level. The corners are welded and ground (a nice touch), the sliders are smooth, the metal sufficiently thick.
CSPS (sp?) is a Taiwanese company; I did a little research about them when I was shopping. They seem to be producing a good product at a good price.
