Honestly, this is a decision you'll have to make for yourself. Your best bet will probably be to find a reputable tuner in your area and have them create a package for you based on your budget.
You can safely daily drive a car with a fairly big turbo as long as you have the appropriate supporting mods and a good/conservative tune. Although it's not outrageous, I've had my particular setup (see profile) for almost 2 years now (~40k miles).
