Theoretically any color can work, but when working with miniDV, green works best because the green channel of the video contains the most data. Blue and Green are frequently used because they sepereate well from skinn tones. Using red behind an actor will make it difficult to key out the screen without taking parts of his face with it.
As far as where to get one, you could search the forums for one of the six billion other posts which has asked this question. Ebay is a good bet, but there are many places to get one.
Lastly, you can put any footage you want behind the actor. Literally, any still frame or motion footage, so your background can come from anywhere.

Depending on what you're doing, sometimes other colors can be used.
I believe in Predator they used red to composite with during the scenes where the alien was invisible... this was because of the blue and green of sky and trees.
And in Hollow Man, they painted Kevin Bacon's entire body green, blue, black, grey, etc. depending on the type of shot they were doing.
When he was underwater, he was completely black, even down to wearing black scleral contact lenses (because black contrasted the rest of the environment the most).

You can also just use a garbage matte and, frame by frame, delete the background by turning the Invert Shape Filter on.
I'm having to do that for a project I'm doing. The character wears a bright yellow costume with a blue cape, so I can't use greenscreen. It is incredibly tedious, but it gets the job done.
I created this clip with an inverted garbage matte.http://www.youtube.com/watch?v=Ao5RZiDbtYs
