Well i've decided to go with a head/cam setup for now. when i need to rebuild i'll go with like a 12psi supercharger on a forged bottom end. That way i can retain the awsme exhaust sound (turbo seem to take that away), plus i will have a lopey idle, and nice while from the supercharger. the best of all worlds. I do agree that turbos are far more efficient, but they do take away from the sound of the exhaust. I heard the sound clip of an STS turbo, and instantly decided i didnt want to go turbo.
