Hmm, if you don't have the room for a beardie, then you can't get the best lizard out there: Blue Tongue Skink!!
However, for limited space the good ones would be a leopard gecko, plated lizard, or Schneider's Skink. All three can be handled, and can even like it, and require a (in order) 10g tank, 20L-30g tank, and 20L tank. :)
