Mei tai. I use my moby during the newborn phase, and then start to use my mei tai, b/c it's very adjustable, seeing how you have to tie the straps. Usually by then though, my patapum (similar to ergo, but less pricey) works too. If you are willing to go one shouldered, a pouch sling would be a cheap option. I keep one in my diaper bag as a, "just in case" sling, b/c it doesn't take up much room and it's nice that you can do multiple holds with it. I've worn my baby cradle style when he was younger. Now that he is 5 mo, I have in him the kangaroo and hip carry. The kangaroo carry though, attracts a lot of attention (from other ppl), b/c it makes babies look so cute.
