Anyone have any experiance with Retro clone video game consoles?

Like the Retron series by hyperkin and the like?



I ask because I'm interested in the Retron5 even though it's an emulator rather than a hardware clone.



Anyone have any experiance/opinions?



I have original consoles but it would be naive to have something plugged into my big flatscreen as well.



Also does anyone know where to actually buy one?
