Buying Monitors

I’m a graphic designer and use a 17″ Viewsonic A75f flatscreen CRT monitor. I’d say within the last few months a problem with colors has started. Most noticebly the black is shifting over to a brownish tint. I tried just about every brick-and-mortar chain store I could think. I haven’t shopped for monitors in three years. So I was shocked to find most stores only carry CRT monitors; with one or two clearance CRTs. And when I go online, all I find is refurbished junk. So my question is… is there a store or website that sells a wide range of brand-new monitors to graphic designers?
