US$57 + shipping from China
For the price, the UDB1108S is a very capable generator and will drive the plasma system very well. It runs off a USB connection so no power supply is needed. However not all parameters like duty cycle and voltage are software operated, so care must be taken when using it. Also the build quality is not up to par. Some of the potentiometers for voltage and duty cycle have shown to be prone to failure. However the price is very reasonable, and for plasma use you’d set the switches and leave them.
The only reason I would recommend the UDB1008s instead of the Spooky2 XM, is for financial reasons.
The full review will be posted later.
