I use my Nintendo DS Lite (US$129.99) and the 漢字そのまま楽引き辞典 (Kanji Sonomama Rakubiki Jiten) which you can get for about US$55 from someplace like Lik-Sang.com. Together the two items still cost less than my Wordtank. I have the V80 and I never turn it on anymore because the DS offers a much better experience. Also the DS plays games like 財団法人 日本漢字能力検定協会 公認 漢検DS Zaidanhoujin Nippon Kanji Nouryoku Kentei Kounin: KanKen DS (a soft for prep for Kanji Test), 漢字の渡り鳥 Kanji No Wataridori (a "game" to practice kanji in general that I have never played but seen), and the countless other kanji practice games that I am sure will be released for the DS.
