Difference between DVI and VGA?

[Coomber1]

Hi there,

I am in the market for a new monitor, I only need a reasonably cheap monitor, the majority of the cheaper monitors only have VGA input, is there any real difference between the two (picture wise) ? or is vga just as good for normal use. I have been looking at around a 22" or 24" monitor.

My budget is of around £150, Which means I can get a monitor with DVI input, I was just wondering if there was any difference between the two. It probably is a sensible idea to get one with DVI input seen as I will mostly be using it for work, (word, excell, e.t.c) and the odd game every now and then.

Thanks for your help!
