At €750, this sits well below your €1,880 25th percentile and far under the €2,999 median, so it reads as a strong deal rather than merely fair. Against the recent EUR comps you gave, it is priced at the very bottom end of the market for this model, which is exactly where a buyer wants to be if the unit is complete and working.
That makes it a worthwhile grab because PowerCell units are sought after for cleaning up hash and grit on noisy mains, and the 12-outlet format gives real flexibility for a full rack without needing multiple conditioners. If the listing includes the original cord, all outlets are healthy, and there’s no sign of prior overload or repair, the upside is solid; at this price, the main thing to verify is simple functionality and that no accessories are missing.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
