What kind of Wall Mount for a Visco 32" Widescreen LCD HDTV? - vesa mount standards

I'm not sure what wall mount for use with this TV ... This site is a VESA standard wall mount for say (wall mount) 200mm x 400mm. But I bought this at Wal-Mart said, that buying under "accessories" to EasyMount a Flat TV wall mount for 26 "- 42" LCD is provided. However, it is said that some VESA 75/100/200 and larger hole pattern. I do not know what the 200 means x 400, or that everything is simply the size or what? I get a 200 x 400? If so, so let me choose the maximum recommended dose of only 200? I'm confused ... recommended a cost of over $ 100 is too much for me, I'm looking for something cheaper, so I ask?
