Video Signal Splitter & Amp

[SuperNaruto]

I need to split a signal out of 1 vga output.. I got a nice 20 ft cable and the signal degrades a bit.. anyone have any recommendation for amp splittler combo ? shouldn't cost more than 100 bucks right ?

currently using http://www.dsgibusiness.com/catalogue/item/BELMK021 with a 20ft cable.. but this is not amp...

thanks
