Supra 6-way mains block - cost around £150+. In very good condition. See for details:

I found this much better than a mains conditioner costing five times more by Isol-8 - very light filtering, with surge protection. Quite a few positive reviews such as Techradar:

Say £80 plus delivery.
Not sure if I have original box, but if not will be well packed.
