>Good earthing or rather bonding need not be expensive. I use the sort of copper tape used for wrapping some sorts of power cables, its about 50mm wide and about 0.1 mm thick (about 5mm^2)and is wrapped in a spiral around some power cable cores. Off cuts or ends of runs are not too hard to get hold of if you can find a local cable manufacturer. Nothing comes close to it for tying two pieces of equipment together electrically. Its thin enough to be bent and curved where ever you need ( and torn across like heavy paper if you have strong fingers)but wide enough to be ultra low inductance.
