It really all depends on what kind of setup the person wants I was keeping track of how much I was spending on this swap but when it got over 6 i just said fuck it gotta pay to play lol. Cost for a K swap can vary greatly depending on what you want...new parts or used parts, knock off's or the real deal. fast/cheap/reliable pick only 2. I'm sure you knew this already im just shootin the shit bored at work...
