Help with finding a monitor to run Dual Monitor

I have an early 2008 Macbook Pro with the regular DVI output. I really want to set up another monitor with my MBP to create a dual monitor set-up. However, I've been trying to do some reasearch, but most of it pertains to the newer MBPs with the mini DVI output.

So I was just wondering what I cables I would need to get the best resolution out of a monitor. I believe it's the DVI to VGA cable I would need for it, but I would like your guyses input.

Also, I was hoping to also use this monitor as a TV so I'm not sure if that affects anything...

As of now I have one monitor that I've seen that looks like it would work but I'm not positive: here it is http://www.amazon.com/Samsung-P2370HD-23-Inch-1080p-Monitor/dp/B002DHS398/ref=cm_cr_pr_product_top

Thanks in advanced!

 

Great! That's awesome, thank you
