Well the market is rather inflated in Japan as classic JBL monitors have quite a following over there.
However all the big JBLs seem to have developed big price tags: here are some 4333As in the US
Here are some of the big 4350 bad boys in France
. Eye-wateringly expensive.
If you can find some beaten up L65s, you might get a more reasonable price and you'll get 90% of the way to the sound.
