Just for information I reckon that I have made well over 300 of these now for all types of scopes/cameras. One thing I have noticed recently is when I respond to someone with a quote/information, that is the last thing I hear from the person. It is only the minority do this, but I think it is quite poor form to not acknowledge someone if they have gone to the trouble to respond to a query, be it a cost query or whatever regarding the light boxes. I used to chase them up, but do not bother any more as it fills the mail box up too quickly.
So people please if I send a response, please acknowledge one way or another so I at least know that you have received it.
