Well, I just received my IOS 13oz from Rockey at USA Kilts, on Monday. Ordered it at end of Feb, and received mid May. Most of the wait was for the fabric, which arrived at end of April, I believe.

The $500+ is well worth the wait. It is tailored just for you, so it fits properly, and cannot compare to any off the rack product. Save up your pennies and go for it.
