Soarer is right on that one, sorry I thought that abbreviation was more well known. All the g84-4100's I have cost £9, and that's including the shipping, Its a bit of a gamble as to what condition you will get it in (one board I have is pretty beaten up but still functional, another looks like it is fresh out the box), but for that price you can't really complain! I guess the key to finding them is just constantly trawling ebay.
