Need new monitor

I'm going to be getting a new MBP 13" here in about a week or so, and I started to look for possible monitors to use with the MBP.

I was looking at the 23" Dell Ultrasharp Monitors and the 24" Apple LED Cinema.

My question is, how often does a 24" Apple LED Cinema go up on the refurb site? and how much?

I'm very anal about how everything looks together in my room so I'm leaning more towards the Apple Cinema. In any case, I don't really use my current mb for anything besides listen to music and do some uni work. Sometimes I'll mess around with photoshop and watch videos but the MBP is mostly used for school and monitoring the stock market.
