[senco-forum] Quick cheap dyslexia screen

I am aware of all the issues involved with diagnosing dyslexia, but nevertheless feel the need for a quick easy test or screen. I have been using LASS/COPS up to now, but find it too time consuming and not definate enough. (I also cant afford to renew the licences!) I have looked at all the older stuff recommended by the forum over the years, but there seems to be new stuff around; 
I need something for children aged 6-11, preferably computer based and must be cheap!
