The price for boot levers was too high previously so I have obtained pricing for the CNC machining to be done overseas. Even so, for a quantity of 24 (12 pairs), the best pricing I can achieve is £38.66 each (£77.32 a pair). This is passing on the devices at cost but there would be a £3.00 postage fee for 1 or 2 levers. As committed quantities go up, the price comes down so an order for 100 levers would result in a forum price of £23.48 each - but I'm not seeing that level of demand.
I'll provide pricing for dead pedal and seat levers shortly. Still trying to grind the prices down (as well as the aluminium)
