I have to agree that xfce in stretch is looking good, but I've been trying to strip it down, not adding more to it.
I took out sofar: avahi, libreoffice, xsane, gvfs
added: mc, pulseaudio, smartmontools, gdisk, mesa-utils
got it to 1.7G of disk space, uses about 350M of ram with a lynyrd skynard album playing.
Still haven't picked a browser yet though, and a lot of other stuff, no screensaver, no aptitude... and synaptic want 200M of updates.
