Amazon has the Fishing Resort with Fishing Rod Controller marked down to $19.99 from $29.99.
This includes the game and fishing rod controller. The reviews on this one are pretty good. Might be a fun way to fish indoors in the winter! 🙂
Important Note: This does not come with a Wii controller and Nunchuk–only the fishing rod controller adapter part. Just want to add this to avoid any confusion.
