I started with a moby and loved it. We moved onto a connecta, you can have them made to order with longer straps and different fabrics. I've also got a ring sling which i use round the house, if i'm cooking the tea, putting washing out etc. I've just had a babyhawk mei tai but i'm not overly keen on it, although i've only tried it on once so i haven't really given it a chance yet.
If you like wrapping, have you thought of getting a woven wrap? If you get the right length you can use them for front, back and hip carrys. They are also much more supportive than the moby so will last forever.
I go to my local sling meet and i get the chance to try loads of different wraps and slings. I hadn't tried a babyhawk before i got mine though but had tried other mei tais. Search sling meet in google to see if there is one near you.
