I need a HDMI switch with built-in optical switching. This HDMI switch by Octava has built-in optical and coxial switching. I need one to connect my Toshiba HD-A1 and PS3 to my projector and receiver. My projector has one HDMI port and my receiver has no HDMI ports. This Octava switch does everything I need, but it costs $274.00. I would like to get a cheaper one, if possible. Thanks for any help.
