Yahoo! Voice or Skype?

Recently I have gone into the market searching for the best online calling program to keep me in contact with some family and friends. I have a few good friends living in Honduras and others in South America. Early next year I myself will be heading to Costa Rica, so I desire to find a cheap and effective way to stay in contact with family and friends. Recently I have been trying out both Yahoo and Skype and I am not sure about either of them. But I know for my calls to Honduras Yahoo tends to be better for the money than Skype. Maybe I am cheap, but sometimes my minutes run down to fast using Skype. Both are okay when it comes to quality and sound. But hey, I am dialing across countries and many waters, I wouldn’t expect it to be crystal clear. What do you guys think? Skype or Yahoo? Which program is the better deal?
