I missed the thread about the cards when it was up ,I don't get on here every day and tend to miss some posts as they go down the board, so I will add my two penneth worth here 

I prefer A+ cards but searched for ages trying to find some poker size jumbo index ones, when I eventually gave up I decided to buy some Modiano's which I think are just as good. They most probably won't appeal to KEM fans as they are a fair bit thicker, which is the reason I prefer them. I tried KEMs and as someone else said in the thread they seem to warp really easily so I never bought any more and switched to A+. Modianos are available fairly cheaply from the States on ebay.
  There is a fairly comprehensive review of different cards here

   Hope this helps,
