Mischief(LTS)

So I'm going to start saving for a turbocharger for my car. I want to know what a good mid-range turbocharger is that won't give me problems. And also, about how much am i looking at total to put turbo in my car, with everything (turbo, intercooler, hookups, etc) total? I was thinking about nitrous but i think this is a better route to getting more horsepower, i dont think the stock engine can take nitrous that well, i could be wrong though.
