content: Eh, I completely missunderstood your initial post. I was under the impression you were selling this unit.If you bought it for 150$, I would say that is a VERY good deal. Particularly outside Europe.Congratulations!Cristian

content: Cristian, thanks, yeah, I'm excited and also briefly tested, it is working fine, not the overshoot yet though.
