Thanks. That was enough information to find it on Konami's website: http://www.konami.jp/products/style_nm0275/
It doesn't appear to be in stock, or even available to be ordered, at least based on my fairly shaky knowledge of Japanese. At least that's what I take "ご注文できません" to mean.
This was published earlier this year, right? One of Konami's pages lists the date as 2010, not 2012, but I'm guessing that's a typo. If it's from this year, I'm willing to spend a bit more effort trying to hunt it down. If it's two years ago, though, forget it.
