Sound like you need a 300 spine shaft.  I bought some Trophy Ridge Crush 300 shafts after last years season and only paid about $70 bucks/dozen (on Amazon of all places).  They are about 11gpi and .0008 straightness.  VERY GOOD shaft!  They are also small diameter shaft.  But, wholly cow, I just noticed that Wally world is selling them this year for $175/dz.  Amazon has some for about $110/dz (shafts).
