Go check daily deals on tigerdirect.com or newegg.com. You can get 21-24 inch monitors on there for 150 bucks depending on what is available open box, clearance, or as a daily deal.
They have a 24" refurbished acer on tigerdirect right now for 169.97. At that price get two if your video card has the 2 dvi outputs and you'd have an insane amount of desktop space.
Total would be under 400 bucks even with shipping.
