where should I buy a teakettle?

Specifically, where should I go in person tomorrow morning to buy a new teakettle? (I dropped the one we had and it broke.)

I don't want to run all over the place, so Arlington, Cambridge, Somerville, or the red line-accessible parts of Boston would be best.

It needs to be a whistling tea kettle, and doesn't need to be fancy or expensive. The kettle it will be replacing lasted more than three decades, and I paid four dollars for it, which is cheap even allowing for inflation.
