Ralph and I were laughing about his Carsteen last night at P1. Not about if it has a problem but when it has a problem good luck on sending it out to get it fixed. At least in his experience and others I know.
Maybe...
I just made a couple of quick searches and found that the least expensive model, that has an adjustable voltage curve feature, is the CS-2. I saw it priced at $450.
Like the Hitman, the CS-2 uses 4 DIP switches. On the controller, the switches are labeled "Profile".
I'm sure Ralph would let you try it Dale if you wanted to.
