I have mostly completed the top half of my panel (early model like Kevin's) and am currently in parts order mode for the bottom. I opted for the 430W in the bottom plumbed to a 796 flush mounted up top front and center. My eye's are getting older and the 796 Screen absolutely smokes the smaller Garmin IFR boxes in all respects. You can shoot flight plans over from the 430, the Wx is more pleasing to look at, it has syn vis if that floats you boat, overlay onto a chart all sorts of good stuff...
It is heavy, and spend, but run modern gyros and you get the weight saving to pay for it.
Since the rest of me is getting older as well, (including patience and hearing) the notion of flying with a handheld for a back up comm in an IFR ship has lost its attraction as well. I love to save weight where I can, but given some of the lighter options out there today in this case 'the juice just ain't worth the squeeze...' If IFR wasn't in the equation I would be happy as a clam with a single comm box and call it a day, for that matter, much of my flying involves no comm box... In the soup I enjoy having frequencies dialed up and ready to go, and the more the merrier, so an extra comm box is not likely to be sitting idle and off in a bag...
Take care, Rob
