I'd like to put my Sky box, Surround Sound and DVD Player out of site. Not being a massive TV viewer I don't want to spend any more than I have to. Would you recommend an IR extender, due to cost, or an RF remote because its so convenient having an all in one too? Other than the Harmony 895/1000 what other remotes are RF? Any good budget ones? Many thanks, all advice greatfully received from those in the know.
