Thanks for the kind words.
I got them here in Singapore (got four pieces in a period of four days, last weekend). They're a bit overpriced at this end, as with almost everything else.
In Japan the prices should be better, I've also seen a couple of U.S. vendors asking $500-800 for the standard models (which is kind of reasonable).
I'm selling my little used MBs, the 146 Solitaire Platinum and the Meierstruck 149 as well. I guarantee you that after trying a Nakaya or Platinum, you'll be hooked pretty well with this type of pen.
I can provide further feedback for those who want so, particularly on how the chosen nibs perform.
