@packrippa – Was it 30,000 円 or 34,000 円? In any circumstance, that is a pretty good deal in comparison to eBay and other websites of a similar nature. I bought mine at 32,000 円 last year. This year, the 30,000 円 spectrum seems to be the average price for this set on Yahoo! Japan.
As for the number of sets in existence, the UPCCC has debated this a few times.
