Hi Mike, I may have 1 or 2 left, getting pretty slim pickings on them now as they are not made anymore. Not sure if it's ok to put my email here, so shoot me a PM with your phone number or email address
The old LNB's are becoming very scarce, Shaw is still pushing installers to replace any we run across in the field. Where I'm at we mainly use 60cm ones and the guy I was getting some from up north is no longer in the biz I'm afraid.
For the main account holder the LNB is a free upgrade if we come out for a service call, if you have another location you would just need to buy a new one for there. There really is no need to stick to the old ones anymore. The only real issue would be that you see the channels in the guide you do not get from the G1 sat.
