farmerdave,
I would recommend buying a new Wii Remote Plus from a local game store or department store. Purchasing an older Wii Remote (without the plus) is tough because I purchased one online and it turned out to be a fake (very poor performance). I would buy from only a trusted source and a local store might be the best bet.
I just looked and Walmart has the Wii Remote Plus on sale now for $34.42, maybe that would be a good place to start

Just remember that with the New Wii Remote Plus, using the Toshiba bluetooth stack is required with smoothboard.
Good luck!
