Just finished a 100 meters of Kota Black Indian Limestone with sets, paid around same price, try Stone and Porcelain in St Helens I had good service from them. The Limestone was only a third of the total hard landscaping cost, slot drains, kerbs and edges, recessed covers, lighting, stone, sand cement, brush in grout at £45 a tub( x 10) machine hire and labour. We did some Porcelain too this was much more labour intensive and slower to put down in herringbone pattern than the limestone. All looks great but its only really black when its wet or you apply the sealer. Well worth spending the money on what you want though.
