So I picked up the F 50mm f/1.7 for $99, so far I'm in love with it. Now looking for a wide and tele part. Saw an used Sigma 24mm Macro on Adorama, looked through the reviews here and thought it might be good. Its going for $124, is it a good buy? Or am I better off going with a Sigma 28-70 F/2.8 EX constant or Pentax 28-105 f/4-5.6??? I'm not going to need a long tele, and I'm keeping budget in mind, since Im currently on $300, so the one I buy has to last me for quite sometime, until I get money again. *off record: this forum is the greatest thing in the world for asking, outside of the Ubuntu forum
