Its all relative. I mean if you want extensive work done and just dont have the skills then its not a bad thing to pay someone to do it correctly. You just have make sure your getting good people to work on your car. Some people arent afraid to swap a motor and some will pay someone to do it because they dont have the skills or dont want to deal with the headaches. As long as you factor in labor costs and can cover it, I dont see a problem with it.

Anyways back on topic. Id say b00gers was dead on. Thats pretty much exactly what i would reccomend for most people for good all around sound.
