Best/cheapest reusable products

I've been thinking about trying out reusable menstrual products. I will be spending a year in a third world country and want to have a reusable system in place before I go. I would like a menstaual cup and a few pads and liners. What are your favorites? I'm almost sold on Diva Cup but where can I get good reusable pads that don't cost an arm and a leg?
