In Search Of The Perfect Infant Carrier

Okay "World O' Moms", I have a question for you.  I'm looking to buy an infant carrier and/or sling and was looking for some good recommendations.  This is what I need:

  • I live in Texas so one that will keep both me and my child relatively cool would be good
  • I have chronic back pain, so I need a carrier that will support my back and distribute the weight of the baby
  • I'm also "endowed" with certain large "attributes" so I'll need one that will accommodate for that
  • I would also like to not spend a small fortune

Anyone? Anyone?  I'm counting on you Internet.
