Been using the Aldi/Lidl ones for a while now, I can chuck them around and not worry about loss or breakage. I have some cheap Riderz ones from Argos, better than the Aldi ones, most expensive ones I bought were Madison D'Arc. Never tried the Bolle or Oakley stuff, can't see £100 worth of polycarbonate there myself. TK Maxx sometimes have the designer names in for £15 on their racks.
