This thread reads like an Abbott and Costello routine - "Who's on First?"
Again - Soltron is part of the Ergoline family (in fact, the Soltron brand has been around longer than Ergoline!). Made in Germany traditionally, although I supposed it is possible that the Jonesboro facility may now be used for some assembly for Soltron or Ergoline.
They are nice beds. Anyone can take good
equipment and make it bad, with infrequent lamp changes, poor maintenance, etc. But out of the chute - they are nice and most salon owners that have them have liked them, other than the handful of salons that experienced significant acrylic issues with one particular series of acrylics. That seems to have been fixed, from what I have heard.
