I think this question was asking about empty cartridges that you fill yourself ala HIELO? I don't have much experience with this, but any standard fill-your-own cartridge should work, it will depend on the consistency and makeup of your vape juice as to how effectively it vaporizes, whether it clogs, etc.

I think in general the refillable mods are better than the disposable carts since you get a higher quality battery, better temperature control, can replace coils, and so on. Here are a couple of threads with more information on those.
