JazzCNC,

I completely agree, after consulting n people I had at least n+1 options! I did consult a lot of people and did my research. I admit being caught out by the USB powered BOB was down to me but every other controller has been based on recommendations / reviews and a detailed set of questions sent to the supplier. Sadly the sales departments of most companies simply say what ever the customer wants to hear and claim you must have misunderstood when challenged after the sale. That's why I record all phone conversations. It won't cost me a penny for products that don't work.
