Re: [CAD_CAM_EDM_DRO] POWER SUPPLIES

There does seem to be a good deal on this alltronics website. Any reason I should be wary of this power one switching power supply? The 24v, 15a output should be plenty for a small cnc. Am I missing something because this is even cheaper and has more outputs and capacity than the supply we've been discussing?
