I'm probably gonna find out I paid too much at some point, but I bred snakes for this reason. It sold at 20,000 yen which translates to $175-$180. Add in shipping and the deputy charge and it may result somewhere around $200-$220. I haven't got the final shipping costs yet because a bunch of other stuff is coming as well. I'll figure out a total once I get the info in a week or so.
Aside from that, I FINALLY found a use for my scanner! It's POS HP software so bare with me until I get a better 1 up. Here's the back of the Doom Island card.
There's quite a bit of wear as you can see, but it shows the monsters nicely. Anyway, I'd heard that Trendmasters had the rights to Kamakiras, but was disappointed when I didn't find him on the back of this. It would be really great if a Kumongra made it out. Only good one outside of the HG line is that Marmit or something (can't remember the manufacturer) and the prototype by Y-MSF (who knows when we'll see that).
