Looking to get a computer w/ cadence on it for my lady. I'm not sure about getting one that's wireless or not. I've seen some decent deals on the Mavic WinTech FS, but that's totally wireless and I've never had one (I currently have a Blackburn Delphi). Can anyone tell me if they have any experience w/ this model, or have any recommendations on a different one? I'm hoping to spend < $50. Thanks!
