My question probably got buried in the long A300CS thread, so posting it separately. I am seriously considering the A300CS as a holiday gift to myself and I understand the steadily improving firmware and software upgrades. My question is whether I need to be aware of hardware versions and whether I should only be looking at units manufactured after a certain date? The reason is that my LDS has 2 units that I am going to go check out this week, but they say they have been sitting on the shelf for months and both have rather old build dates. Will upgrading the firmware bring these units up to where a freshly manufactured one will be? The LDS doesn't seem to know, so thanks for your insight!
