The Konica Minolta document center in the workshop is on a dedicated surge suppressor (ESP unit) as recommended by the Konica Minolta service tech, which I picked up from eBay (the surge suppressor, not the tech) for around $150 a couple of years back. The laser printer in the closet is on a APC UPS surge only port that was, AFAIK, rated to handle a laser printer, specifically a HP3600n. I suspect that most lower-end or consumer grade UPS devices, and certainly an $8 surge suppressor from Best Buy just ain't gonna be up to the job.
