For those who like to tweak/experiment - highly regarded in its day -an Ortofon OM-10 turntable mat. Thick rubber-ish construction, though from what I recall it isn't rubber but some fancy deadening compound. I used to use it on an early Nottingham Analogue deck - so I think better suited to non-suspension decks. It worked very well and it's going cheap. Anyway £30 + £3 postage. PM me if you'd like it.
