To take advantage of currency parity I recently ordered the Suiter and the Rutten/Venrooij from Amazon, total cost $US89. They quoted an ETA of 30-Nov to 31-Dec but both books arrived a week ago
This is both fast and cheap, considering that I have been unsuccessful getting those books 2nd hand for a reasonable price, after my original copies went "missing" (never returned by borrowers)…
Cheers
Steffen.
