Yes it was just the vsa issue that caused me to change over, for some reason i just could not get it working all day and the data went all haywire.
I have been with tenfore for about four years now and although they are more expensive than BIS i just feel used to them now. Not had any problemss with the satelite feed.
I think that if there are any problems that they are with the pc or the software loaded on to it. My colleague uses vsa and had problems, he now uses bis and his machine is more stable???
