Smat yer Banter! ;)
I have two 857D's. They are excellent do-it-all rigs, but there are better performers.Abused 'em, used 'em, and I've become used to the menus so I don't have to look. Both programmed the same, and one of them has the INRAD 300 Hz and 2000 Hz filters installed... a big help on HF. The current draw on RX is a bit high for a backpacker setup, but I've done it.
FT-817 is better, but QRP. And the FT-897 does have that lower voltage battery pack, I seem to recall an RX current draw that was in between the two.
I'd consider the purchase of a do-it-all rig like the Yaesu 817/857/897 series, the Icom IC-7000/706, etc. used in excellent condition.
And have enough left over for antennas, and a better "base" HF rig, also used. There's some excellent used rigs out there.
