I am looking to get the AKSA amp kit, but I'd like to maximize my $$ since they are from australia. Is there a public way to get curency charts that show the value of the US$ relative to the AUS$ plotted agaist time? sorta like the those 5-day and 1-year etc charts that you can get from etrade's website on regular stocks. perhaps etrade has it, but I have no idea how to look it up. thanks!
