It looks like the cheapest would apper to be richer sounds pricebeating unbeatables £160 offer for the black version, making it £150. Cheapest for the silver would be £175, with richer sounds price beating digital direct. However richer sounds desn't specify whether the fx 5.1's they stock are the black or silver versions. Hopefully I'll be able to get the silvers for £150 (£190 including supercare), but most probably unlikely.
