If you think in terms of re-building a whole new FF system, that's OK. But most people think they can just buy a supposedly cheap FF body and put all of their good ol'glass back to work as they used to. That's doable, but the resulting performance won't necessarily match or surpass that of an APS DSLR equipped with a 10-20 or 12-24.
