Maybe to expensive...
DP832A is cheaper and looks like better Specs.
As a seller will not comment directly on the price, that is up to the potential buyers to decide. I will just say though that on fleebay these typically go for +1,000 EUR used. Will not mention/use as a reference the price when new cause one may fall from the chair.
You're probably not familiar with Toellner since comparing it with DP832A. As a hobbyist one can definitely be served well by a DP832A, but even so and just to set the record straight the model I am selling has double the power, double to output voltage and more than double the output current of 832A. That is before we go in other performance aspects.
