The Asus 22" monitor pretty much has to be a TN Film screen. They are as low end a screen as can be bought.
The HP screen mentioned is an H-IPS panel, which is very good.
When I recently upgraded, I went with a LaCie 324, which is an S-PVA panel. I chose the LaCie because they specialize in professional grade screens designed for photographers and graphic artists, so I figured that they probably are better from a photographers perspective.
I just published a book of my photographs, using the LaCie for the editing.
My trial copy arrived from the publisher (blurb.com) today, and is EXACTLY what I saw on my monitor.
A good monitor won't be cheap, but unfortunately, a cheap monitor won't be good.
TN Film displays are 6 bit colour, or 64 colour shades per channel, the LaCie is 10 bit colour (1024 colour shades per channel).
Compare this to a jpeg, which is 8 bit colour (256 shades) or the 12 bit (4096 shades) that comes off our cameras, and you will probably decide that a TN film monitor is not for you.
(The above is presuming I am interpreting things correctly.)
For sure the LaCie looks better than the Samsung, and is (IIRC) 95% of Adobe RGB colour space).
Look at Mark Roberts' blog on the subject, and follow the link to TFTCentral where you can input specific monitors and find out which panel type is inside.
One thing interesting though, a thread that I read the other day had a fellow complaining about a streak running through his high ISO picture. It was very visible on the Samsung 225 monitor which is what I use as a second display, not visible at all on the Lacie until I had seen it on the Samsung and knew where to look.
