Does anyone know of a switch i can use to save me from connecting my PC and PS3 the monitor each time i want to switch?[quote]
That's almost why I got myself a S-PVA panel 20" 720p LCD tv to replace my VP930, though my problem wasn't of switching connections but that the DVI wasn't HDCP compatible and the extra cost of a decent hi-res supporting VGA box (which might be what you need) might as well go towards a new LCD, plus the VP930 should fetch back at minimum 75% of it's price.
This link might be helpful for you, though if you are using HDMI/DVI at the moment you would need to get a component lead as well. It is one of the possibilities I looked at whilst researching how to get over my VP930's non HDCP problem:
