I think a Masters could be a good idea, if you don't yet know your interests. You don't want to get accepted into a PhD program only to realize halfway through that they don't have anyone working on what you're interested in.

There are not many funded masters programs in the US, but almost all masters programs in Canada are funded, and I'm not aware of any math departments that don't have an option to do a masters in pure math (it may not be a separate degree at all - just a masters in mathematics, and you specialize however you like). The funding is not always fantastic for international students, but tuition is much, much lower than in the US, and in most cases they will provide enough to live on if you are frugal. Some schools offer very generous funding, in fact.
