Cheap monitors are easy to find. Go to most computer hardware outlets and you'd see plenty of off-brand, "get the job done" monitors (and by "job", I mean delivering images to your optics) awaiting your dollar.
However, just because you're paying $150 or less for a monitor, doesn't mean you're necessarily getting a great deal. Paying $150 for a monitor with a paltry feature set, thoughtless design, or lackluster performance, could induce an annoying and probably unexpected sense of buyers' remorse.
