I'm wondering about getting a PS2 for the bedroom, but have one sticking point.

I've only got a HP 20" widescreen monitor - the VGA port is already taken up by the connection from the laptop, so its only got a spare DVI-D port. Is there any way of getting the PS2 signal through to it? I've had a browse, and can't find any cables. Seems like the only way of connecting would be via a variety of adapters .... by which point I'd be getting close to Wii pricing?
