is there a specific reason why you would prefer a monitor 27" up to 32" ?
two reasons i ask this:
- at that price point you might get a lower quality than what you would like instead of getting a better monitor at a lower horizontal size
-the common 1920x1080 & 1920x1200 resolutions available at that price point will not look any sharper if you blow them up as such. if anything the image will look worse than if you used a 22" to 24". the photoshop (or whichever) program supports zoom so this would be the ideal way to enlarge objects.
that said... if you are looking for a graphic design monitor you should give viewsonic a look.
if you absolutely want a larger monitor you might want to try this:

the price is higher than what you stated but you might be able to find a deal somewhere (sometimes at computer shows).
if you dont mind going with a smaller monitor you might want to try this:
http://www.viewsonic.com/products/desktop-monitors/lcd/...
the price is below your limit.
i've had excellent luck with viewsonic. their IPS panels are crisp with great color and some even feature rotation if you want that. I used to do some graphic design on the side in the past for fun and i used an older vp201b 1600x1200.

fyi,
for displays at your requested 27" to 32" the most commonly recommended display is the dell ultrasharp 30" (forget the model number) but it goes for over $1000-1400 so that is completely out of the question. the nice thing about said monitor is it features double the resolution of typical monitors.
