Xele is on a role picking stuff up. You just added an awesome game to the collection, hope you give it the time it deserves!
You getting these games from Yahoo Japan? It took me a long time to find my stuff, you guys all seem to have a better source than I did!
Heh, I did a lot of ebay shopping when I first got into LaserActive stuff several years ago, but there is a lot more competition today. After that I went for overseas stuff since almost all the games are multi-region. Most of my JP games are from Yahoo Japan or Surugaya, there are a couple other retailers I've found that occasionally get LA stuff in stock so I check back periodically on them as well.
Really though, I've learned that a LaserActive game not having the obi is my best bet for finding a deal, prices tend to go a lot lower than normal without them.
