I just had Buddies do a ball. I shipped them one I really like the feel of, they checked the measurements, drilled the new ball, and sent both back. The initial fee of $50 covers shipping both ways and the drilling. Further balls drilled are $20-30 (I think) depending on grips/layout... Anyway, the ball they did looks perfect. The thumb slug is perfectly centered (surprising how many places are off the mark), and the milled oval fingers (no inserts) and thumb pitch feel exactly like the other ball. I'll have to throw it a to see if I need to fine tune the bevel, but it's by far the best drilling I've ever had done.
