Are all stock driveshafts of the same quality?

Should I then just go all out and get a new one for $400.00? Is there a cheaper route that would do?

Thanks!
in the grand scheme of this build, with everything you want to do, have you actually figured out how much $$ this will really cost?
and out of that how much is the $400 i guess you've priced for a drive shaft?

6% ? 10% ?
money well spent in my opinion
