What is good CHEAP display port monitor 17inch or bigger?

[king smp]

bought a hd 5670
I want eyefinity for application work
not gaming

i have a 21.5 viewsonic 1080p 16:9 1920x1080 and
a samsung syncmaster 16inch (?) 1024x768

so I am ok with varying size and res

I just need the cheapest but decent display port monitor
preferably viewsonic,asus,samsung,dell,hp etc

17inch or bigger with at least 1280x1024 or better res
using displayport

anybody have any personal recommendations of something
you own?

You can just buy a displayport adapter rather than restricting your monitor choices to one that natively support it.
