Depending where it lands price wise, skip all the complicated switching arrangements, and just run more than one of them, have one each dedicated to a band, at least for 6&2. By doing that you gain the ability to be on both, or multiple bands at the same time. The usefulness of being able to do that is hard to overstate. Don't know if the USB connection in the Sentry would allow more than one physical radio per computer or not, USB devices (and/or USB connected software) can be finicky about that kind of thing. Being restricted to one radio per computer would certainly add cost. That was one of the key compelling reasons I went with the Ethernet connected OpenHPSDR gear. Makes it a piece of cake to connect multiple radios to just one computer. Because of that I can and do run the 3 OpenHPSDR radios plus a Flex 5K all on a single computer that cost about $1000 in total including 2 nice 25" wide-screen monitors. Looks like the 10W input "mid sized" bricks for the 50-432 bands run around $350-400 new, of course less than that used. But you would end up with around 150W on 6M, around 160 on 2M, 120W on 1.25M, and 100W on 70cm. All of which are a bit higher than what the typical knobbed DC-daylight radio can do.
