I would add to your list of serious manufacturers a couple of other names, german Ersa and american Metcal and Pace.
I would stay away from cheap chinese manufacturers, they are not worth the trouble..quality is generally questionable, poor temperature control and so on.
There's nothing worse and more frustrating in my opinion than trying to learn a new task with the wrong tools.
Ersa is available on Amazon in Europe too, which is by far the best seller out there, even when compared to the service level of the historic suppliers.
