It arrived. I did a power on (via hardware switch) test when set to 5v / 200mA and no load and I don't get a spike >5v, although it's close. I've tried this in various modes (peak, normal, hi-res, 20m BW limit).
I'll do some more testing later with different voltages and loads. So far I'm very happy with it and it's a great upgrade to my Farnell L30-2
