Anyone ever used a Multiplaz welder?

I tried to do some Google research on these after seeing your post. The demos I saw all showed 2 pieces of metal that were laying side by side being welded. It would be nice to see some overhead welding and possibly some sheet metal (body panels) being welded. They say gasless and almost no spatter. I do like the combination of being able to cut and weld with only 1 machine as they advertize too. It sounds like a new one sells for about $2000. I guess I'd like to hear from anyone that might have used one too.
