Hi guys,
I've done a bit of calculation for myself and thought I'd share it with you comparing the iPhone Upgrade Program costs with a 0% credit card.
It can be viewed here:

If the OP wants to post a link to it on the first post so others can view, feel free. The short answer is that the credit card method works out better, although you'll have to be sure you can sell the iPhone above a certain amount (see the document). Everyone will be different - some would rather pay out more for the simplicity of the iPhone Upgrade Program, while others will rather go through a bit more effort and save some money.
Hope it's useful for others

Didn't realise that the upgrade option is
only available for those taking out the plan with AppleCare+ included
