Guys, I'm looking for a cheap method to hook my NES up to a new 4k TV. Composite, S-Vid and R/F inputs are gone on this baby. Component is a 3.5mm jack with another 3.5mm jack for the audio. Now I've got a component switcher box incoming, which should fix most all my other device connection problems, but I'd like to hook up my NES, and all it has is RF out (it's the top-loader, and those don't have the side RCA jacks).

Recommend me a good "R/F -> composite" converter?
