That article definitely has a lot of great info in it. I think the only thing that has really been debunked from that article is the Ultrasuede. Chris Pappas wrote up an equally informative post over at the RPF that had a pretty interesting idea as to why the Ultrasuede myth began in the first place. If we're lucky maybe he'll re-post some of that info here.
Buttersuede is an almost exact match. However, a few years ago they stopped making it in the correct color. It is certainly cheaper than the Ultrasuede.

The tan is a tad light for the pants and tunic, but definitely looks close. The brown is the darker material my jacket was made out of. You can see a picture of it over in the uniform resource thread.
Now, having said that...I think it would be awesome to make a jacket out of Ultrasuede! There was a guy a few years back doing them that way and they looked sharp! However it would cost close to two hundred bucks in materials.
