Is there any crypto currency that is feasible to mine on consumer hardware and worth while?

Watched the tek, and yeah bitcoin is no longer really feasable from what I gathered on gpus since the butterfly labs stuff is costly ($4k) and even 7970 are sort of not enough. But other stuff, litecoin dogecoin ect, from the way I understand it is still feasible on consumer level hardware. I'm not looking to start mining I'm just curious now, thanks to the tek.
