Corsair have been getting a lot of flak recently, if you check out many of the overclocking boards you'll see people saying they are not as good as they used to be, and sometimes, they are actually quite bad. Are they sponging of their past reputation? Who knows - but I am not going to risk spending £200 on them.
Hence why I too would prefer scan stock Gskill or Geil or Crucial etc
Personally, at the moment I am going to buy GSKIL to go with my next new build (if scan don't stock them I'll have to get them eleswhere).
