Good place to buy refurbished monitors?

[Parasitic]

Ok well I think I'm set on getting that Hanns-G LCD at Newegg.


Now I was wondering about dual monitors. My nephew said that if I lent him $550 until his unemployment check arrives, he might give me his 20" LCD TV. If he doesn't give it to me though, he'll definitely sell it for super cheap.

Assuming I get both, how exacly do dual monitors work? I think it'd benefit me most when I'm making music since I always have a ridiculous amount of windows I have to navigate through in the programs I use. What common uses are there for dual monitors?

Now the lame part is, my current PC's built-in vid card won't work with his TV (we tried it today). The amount of money it'd cost to get a new case/psu/vid card would go upto about $150, so I'm still not sure if it's worth it or not.
