question for ppl who use a monitor to game on

Im looking into buying an HDtv or a monitor to play my 360 on. Ive seen it on my friends 57in song and it looks amazing but that price range is way out of my league. Im thinking about getting a monitor because there cheaper, but what i want to know is, will the quality of the picture look anywhere as good as an HDtv with component cables compared to a pc monitor with the VGA cables. Which should i go for?

thanks for your advice, ill probaly go to best buy in the next couple of days to check out some monitors. Hopefully someone there can help me find what im looking for.
