I recently bought a PS3 and want to hook it up to my Dell 2407. But my problem is that I have Xbox 360 connected to the VGA and PC on DVI. I don't wanna connect PS3 to the component as everyone knows it sucks on the 2407. So I read that what I need is a DVI switch for PC and PS3. Any suggestion to which switch I can get? I saw some are just $20 and some are in the $100+ range. Is the difference really that noticeable or it is only brand thing?
