From the reviews I read online, the Samsung 151S is a great monitor. Plus, it's hard to beat a 3 year warranty. They extend it by 6 months if you register online soon after purchase, so I'm covered until December of 2006. Bonus!

Just based on price, I picked up a Samsung 151V 15" LCD (black) about a month ago. I'm very happy with it. I got a 152N for a friend, the base is a little different, and the bezel is silver. It actually came with a wall mount in the box, I was very surprised. I like his better.

I had a Viewsonic VG150B for a few months, but I like the picture quality on the Samsung soooo much more. The text is alot sharper. If you can get them for under $270 I'd say that's a decent deal, I paid $256 after rebates from CompUSA.
One thing though!! Black LCD's take a little getting used to. The screen is very bright against the black plastic!! I'd go with a silver/black combo if you can. They tend to be a few bucks more, but if you skip a pizza or a few drinks, you're even.
*edit- My Sunday morning ad browsing found the Samsung 151V for $219.97 at
CompUSA. Print that page and bring it in to get that price. That's $10 cheaper than they had it last month!!
