Do you use those extra buttons for memory and over current/voltage set? I see there's a model kd3005D with two knobs instead of buttons. It seems like one knob got current and one for voltage is all I would need but I'm not sure.
I remember setting the memory buttons up, but I don't actually use them. The KD3005D is probably fine, too. Personally, I'd still prefer fine-adjusting voltage and current via the incremental encoder and pushbutton of the KA3005D. The price difference around here is ~20%.
