I know a few of you carry these units. I have been looking at this model for a long time. I recently came across a deal on one and I have a few last questions before biting. It is a huge unit...do you have reservations about the weight? They claim to have great reception ans ability to hold the sats (the main reason I am so enthused about this particular model)...can you attest to this in your experience? Lots to power there...what is your experience with battery life?
