Well, yes I have a Sony G220 17" monitor which looks great next to my Powermac.
I got it from the Gateway Accessory Store for $294 with free shipping.
I suggest that you go to techbargains.com and look for a discount coupon.
Yes the Sony is a little more expensive than other brands but it has a great display as well as looking surprisingly good next to the Powermac.
Try techbargains, they usually have discount coupons from many popular sites.
