The Dragonfly would be to small if you want slightly smaller than the PM2. In the non G-10 realm of things I would highly suggest the Delica 4. It is a extremely excellent knife for the money and comes in all sorts of colors and blade options such as steel types, plain or combo edge, FFG or Saber grind, black or satin blade.
The Tenacious is a great budget knife with G-10, but is "taller". The Tenacious might not be smaller though. I would have to compare the two.
The Stretch is a great option as well and comes in a few different blade steels to choose from.
