Sorry I cannot help with wireless. Is there a specific reason you want one that is wireless?
I have a Polar H4 heart rate monitor, works great and was on sale at Target. I use it on my bike, running, and for HIIT. On my bike I have Cateye Astrale 8, which works beautifully and was also not expensive, but it is not wireless. I think I bought both for a grand total of $100.
