Well, if you got a big, sturdy, table with lots of room you could always go with CRT's. You could get a 21" CRT monitor capable of displaying 1600x1200 at 100Hz for pretty cheap (a Trinitron from the mid 2000's). They get great color, and have very even black. But the problem with nice, big CRT's is that, well, they're big. They're heavy too. So make sure you have a lot of room if you want to go that way.
But, if you're not into big, heavy monitors, I would recommend looking into used LCD's, or holiday sales at stores. A relative of mine picked up a new 24" Samsung LCD that displayed 1900x1200 that was on sale at Wal-Mart for a little over $120 when it was on sale.
