I've got my eyes on a Casio XD-GF9800 but not sure of the best place to get it.
This place: http://smartimports.net/product.php?productid=16298&cat=23&page=1 sells it at what seems to be a reasonable price, but I'm always hesitant to make somewhat large purchases from companies I've never heard of on the internet.
I recommend [url=http://www.whiterabbitpress.com/catalog/Casio-EX-word-XD-GF9800-Japanese-English-Electronic-Dictionary-w-p-16656.html]White Rabbit Press[/url] or [url=http://benippon.com/shop/index.php?cPath=6_1_3&sort=0d&filter_id=]beNippon[/url] but the latter doesn't have the model you want.
