Could anyone recommend Finishing tools, files etc for CF - that are available in the UK?

I find anything diamond coated to be good.  For example, I picked up a set of diamond coated files from TK Maxx for 6 quid and they're great!  The only downside with regular metalworking tools is that they blunt off quite quickly with composites.  I knackered a few bandsaw blades this way before buying diamond coated cutting discs (silverline ones from ebay, cut quicker than the permagrit one I have!!).
