I am one of the few that flies glow fuel at my field too. I hope to retire in the next few years so I am stocking up on kits I would like to build in the future. I should probably buy a few engines too as they are slowly disappearing and getting more and more expensive.
i do love going out to the field on a calm evening and flying small electrics. There is no way a glow motor would be able to fly a 18" warbird.
Each mode of power has its place in the hobby, but glow is definitely getting the smaller part of the pie
