If you are concerned with weight, the Elecraft KX2 is 1/3 the weight with double the power. It is also a more recent design, with DSP filtering. Battery and ATU can be internal, so fewer cables to connect, lose, whatever. An HT and a KX2 might weigh less than an FT-817.
Seven years ago I bought a KX3 because I didn’t want to carry an FT-817.
