Maximum 24 inch LCD suggestions?

Hi guys,
A new topic for me to start. My wife and I just bought a house, and the sellers decided they wanted to take their TVs with them, but leave the mounting hardware. In the bedroom, there is an Omnimount swinging arm mount, and based on my memory of what it looks like and my research on the Omnimount website, I am thinking the maximum size it is supposed to take is 24 inches. I was hoping to install at least a 26 inch model, but that seems out of the question right? Even if the weight of the 26 inch model is under the maximum weight the mount can support, I should only go with the 24 inch TV right?
If that is the case, does anyone have any suggestions on good 24 inch LCD TVs? Based on the fact I was going to spend around 500 for a 26 inch TV, I am hoping to spend at most 400 for 24 inches. However, any suggestions are welcome.

I went to Amazon.com and found 3 promising choices in the Samsung line, and happy enough, 22 inches is small enough to allow for shipping to Hawaii! Anyway, these are the three choices that I found:
Samsung LN22A450 22-Inch 720p LCD HDTV, Black $384.98

Samsung LN22A650 22-Inch 720p LCD HDTV with RED Touch of Color $429.98 (I know a little above what I wanted to spend, but if the reviews are good enough from you guys that it is worth the extra money, I will be willing to spend it)

Samsung LN22A330 22-Inch 720p LCD HDTV $398.95

I am surprised the 450 model is cheaper than the 330 model, since isn't it normally the higher the number the better? Based on the Samsung website, the biggest difference between the three would be that the 450 and 330 models do not have "game mode" but since it is mounted in our bedroom, gaming is not an option anyway. Also the resolution is higher in the 450 and 650 then the 330. And also the 450 and 650 have DMIe feature, anyone know what that is?
