50, if you've read the link that Centre Punch kindly provided, you will have read my thoughts on the CED. I have ordered an Oehler mod 35 through a third party in the UK and am waiting for delivery. From researching the forums here and on other sites, I think the Oehler may be better than CED by a long way.
I'll let you know once mine arrives /ubbthreads/images/graemlins/wink.gif
