Torn on display options for eyefinity

[automag928]

I'm building a new desktop rig, nothing crazy i5 750 w/ 5850 but wanted to take advantage of eyefinity for flight sims and FPSs. I currently have a Dell 2005FPW that I've owned since 08/2005 and its a great monitor, but I need suggestions on what I should do for multi-monitor setup. I'm not looking to spend a ton of money but want something decent. Should I get 2 more 2005fpws refurbed and the dvi - displayport adapter, or one more 2005fpw and some other brand 22" 1680 x 1050 screen to make my center display a little larger, or should I just get 3 identical monitors and sell my current 2005fpw? I'm torn and need suggestions.

Thanks!
