[Shogi]

$600 on a loose Fort Max (This was back in 2001 just before the release of car robot's fort max)

$325 on a boxed Star Convoy

$120 for a new (At the time) Japanese God Ginrai re-release. Little did I know that if I waited 2 years I could buy it at TRU for $30 on clearance!

This is one reason why I switched to GI Joes the most I've spent on them is $300 for a USS Flagg
