Save the money and buy a compact 100w rig to start with. An FT 857 is the comparable size of the 817 but you won't be outgowing it. When you tire of running it QRP you can crank it out without spending money on an add-on amp for 100w. Never made much sense to me to begin pwr hamstrung when for about the same money a big rig with added features is within reach. Again, used rigs are plentiful from reliable dealers who take trades.
