Parts after the final round

Yes I strongly recommend the First Aid repair kits, extra inner foam, extra flippers/springs, and extra key sets as the key top surface texture wears down after decades of usage.  After the order window closes, they will not be available to order.

Are there any parts you’d recommend buying if I plan on using this board for as long as we still use keyboards?

Nope – please order all needed accessories before the production deadline!
