As much as loved my Flex 5000 and my first 1500 and just SDR radios in general I can't see ever investing that much money in any brand of radio. My XYL about had a fit over the price of a 5000. You can still buy a semi decent automobile for what a 6500 cost. I envy you guys that can put that kind of money into a radio. This isn't meant to be a criticism, just sort of an observation.
To me it's like owning a Lamborghini in a country surround by water whose max speed limit is 35mph! I doubt most people who buy this radio do more with all the extra features other then show them off to other hams. Honestly, unless your like me and just want to make things more complicated than they need to be, simple is better. More interesting to me is if they make a major leap in sensitivity. Don't care for slices.
