Moby Wrap

I am thinking of getting one of these to carry this baby around. I have read some good reviews on it. We have one of these, we got it from Mike's people at work, but I don't think it will be good until the baby can hold his head up, at least pretty well. Maybe like 8 or 10 weeks? Anyway, I do have another sling, like this, but I think I want to try that Moby Wrap. I have a friend that's done with hers and I might wait and try it out once I have an actual baby to put it in.
