I'm using an Emtech ZM-2 with a nanovna for tuning. I'm feeding a loop antenna with a balanced line (or more accurately, my entire antenna and feed system is a single length of wire) so a tuner that functions simultaneously as a balun is a good deal for me. Tuning graphically with the nanovna is pretty quick, I'd like to install an SMA connector and a switch to bring the VNA in and out of circuit rather than connecting and disconnecting coax though.
