I've never played the game, watched the anime, or read the manga, so I can't really give any opinions about it. But here is some stuff I found from some quick browsing, if it helps at all.
"Professional" game reviewers have given it a failing grade, if that matters at all...

My suggestion is, since places like BlockBuster are unreliable, check out some videos on some game sites. Here are a two.

Amazon has it for 29.99, just type in "Eureka Seven Vol 1 The New Wave"
GameQuest has it too.
