David,

I found a US retailer selling the SAITO models and steam engines

http://www.loyalhannadockyard.com/Saito.htm (steamengines) 1,350

http://www.loyalhannadockyard.com/DELTA.htm (model kit) 1,899

http://www.loyalhannadockyard.com/SaitoB.htm (boiler) 698

Totals 3,947 USD.

I bet you better wanna do the real thing for that money :-)!
