My sister sent me a link for a free (yes, you read that right - FREE) baby sling! They are really attractive and look like they are easy to use. I just ordered this teal one (see picture) and only paid $12 for shipping. Twelve bucks isn't bad when you consider it would more than that just for the fabric! I'll let you know in a few weeks what I think of it!
Get one here at Seven. Use the promo code 'colorado'. I don't know how long this will last.
