Thanks Jeff. I think I'll order one today as it's such a great price and it will get me up and running straight away whilst I play around with all of the other recommendations. I will definitely make the additions that you describe. Could you advise how to know what part of the circuit board to ground. Also could you advise how to attach the toroid current choke thanks so much. Perhaps if your ever in Ramsgate give me a email and you can come out for a sail.
