Strollers: Toddler, Ergo

Ergo for a Toddler?

Hi Moms! I am seeking that perfect baby carrier for traveling abroad. For those Moms that own an Ergo, do you still use it for toddlers? Would it be comfortable to have a 30+ pound baby in it for day long trips? I am deciding if I should get an Ergo or go more substantial and get a Deuter Kid Comfort III. Any suggestions?
