Like the Spitfire of WWII fame that inspired it's name, the "high tech" yaw
string improves again, with the MKIV replacing the MKIII. Front line units
are already being equipped with the IV.

Normally I throw away old stock if I've made an improvement, and start
selling the new, better one right away (probably not smart from a P/L
perspective). This time I've decided to sell the limited number of MKIII's
remaining at clearance price of $6 USD, 40% off the regular price of $10.
