B&M vs Transgo opinion and budget $$$

Ok guys beside the transgo tf2 whats the best "simple" shift kit to install ( firm shifts ) , 2500 stall , 360 duster / 3.91s , some places said the trans tail housing needs to be removed and some says it doesnt , the new 727 is back in the car and i dont want to spend a fortune and pay extra hours to my trans guy , i would love a firm / hard shift but dont want to spend 3-4 extra hours of labor for a tf2...
