ISO of a carrier for a toddler 21+ pounds

I am in need of a carrier for my 21+ pound DS and instructions/ tips on how to use it. I have used a sling and the store bought carriers, but never a wrap. I have always fantasized about using a wrap, but I was always so afraid that I would do it wrong and DS would fall out. So, I am ready now, and I will find help, even if it means seeking help here from a generous mom who is willing to walk me through the tying of the wrap. Anyone have a wrap or carrier appropriate for a toddler in the summer that they are willing to sell?
