Yes, I have one of these and it works just as good and as easy as they say. The nice thing about it is that it doesn't require a ground clamp (unlike other plasma cutters). Thus you can work with non-conductive materials as well. Also you don't have to work with a really short stand-off distance on metal like with regular plasma cutters, if for some reason you can't (tight corners, etc.). It also welds and brazes.
I don't have any complaints about mine, the only reason I don't use it anymore is because I bought a larger, higher-power, Thermal Dynamics plasma cutter that cuts faster, and I only work in metal, some of it pretty large (sometimes 8" H-beam). I've always done my brazing and gas-welding with Oxy-Acetylene and I guess old habits are hard to break.
Mine came with a carrying case, and a complete set of spare parts. I haven't used it in probably a year, and since I've got my T-D machine setup on a cart in my shop (where it's readily accessible), I really don't foresee using this in the future.
In fact, if anyone's interested, I would consider selling mine for about 1/2 price ($1000). P/M me if you're interested or want to see pics.

The pure practicality of it, the small size, no need for gas, simple operation makes me believe that the manufacturers are making a marketing mistake. They should mass produce it to lower the price and sell it as an allround tool for the hobbyist market and for small workshops or mobile use. It's a perfect tool for that market segment.
As far as I can see, I can do everything with it that I could do with gas, but with a small device that fits into a bag the size of a large laptop computer bag, without the need for gas. I also find it slightly easier to work with than gas. "

I think the only reason for the high price is that they don't mass produce them. If they would get some backing from a major tool manufacturer, they would reach more customers and it could probably be produced for about the same price as a half-decent MIG (say $500 or so). As long as they produce them on a small scale and sell them only through their web sites, they will be expensive.
-----------------------------------------------
The practicality of not having to use gas is a huge benefit for me, as I don't have any really suitable place to store gas. One thing that's also important for me is that it's not as "sparkly" as a MIG, which is useful if you don't have a suitable metal workshop and don't want to burn down the house becuase you are sitting with all your attention on the weld. I also like the fact that ordinary gas welding goggles are sufficient, as I find them easier to work with.
