from my perspective, a tech degree in audio is a fantastic idea as long as it's something you're doing for yourself and not what you are banking on for a career or any sort of reliable job. for me, it was incredibly self indulgent and helped me get so much more out of my favorite hobby (making music).

as far as schools go, i think you get a lot of bang for the buck at the school i went to in tempe. back then it was $13,500 total tuition price for the complete 10-month program. full sail is longer and probably a more complete program, but at the time i researched it, tuition was around $30,000!

of course, you might just be better off spending $13,500 on some sweet ass recording gear and just continue doing your own recordings as you will get better and better.
