I had a Mei Tai, custom made by a friend here:

I couldn't nurse in it, but I know she makes other types. The Mei Tai was great, I could just put her in, and I had FREE HANDS! It was miraculous, especially with two other ones aged 4 and 2 to contend with. I wore it for hours a day some days.
She does have other kinds, and I can vouch for her quality, it's amazing. My picture is in the Photo gallery, I had the fuschia brocade fabric with velvet straps.
