If you need a cheap 8MB model, definately lean towards the 3xe. Considering that it's definately "nicer" than the m105(bigger screen, more periphials), and can be found for a heck of a lot cheaper than the m105 or Visor Deluxe(The Deluxe is a pure 3xe clone, but without flashROM for the OS), it's definately the one to pick.
