ok, let me make it easy, :
1999 Episode 1 was released new figures were released easy to get,
2000 not to good year for collectors poor distribution & rare,
2001 excellent year for collectors,
2002 Episode 2 was released new figures were released easy to get,
2003 not to good year for collectors very dry, poor distribution & rare,
2004 excellent year for collectors.
The year after the movie release collectiing sucks, the year after the sorry distribution year, it gets better.
