Have fun looking thru these Android TV boxes, most of the quad core ones are good to excellent, the major brands have online support & have recovery media and provide access to updated firmware released, so it can be easy to bring it current - procedures are different depending on the specific make & model.

Depending on what OP is looking for, these might be fun ... most of the live shows and/or programming being streamed for access are in the Chinese language.
