Something you may/may not wanna do is get a nice monitor from Ebay. I got an HP P1120 (used, not refurb) for $275 shipped. Its a 21" monitor, trinitron tube, .24mmAG and all the other goodies you want....plus it supports two inputs (so you can hook 2 comps into 1 monitor...pretty sweet).
I think its a kick ass deal if you wanna spend time looking up stuff on Ebay, took me about 2 weeks before I finally found this awesome deal on ebay (but it is WELL worth it, no problems with monitor and its better quality than any other one I got).
