Does anyone have any experience with portable induction cook tops, like the infomercial branded Nuwave PIC? I'm very skeptical of the high price shipping charges associated with the Nuwave products. I'm asking because my brother-in-law just told my wife about it this morning and thought we might like one for our unfinished kitchen (in a stalled phase of home remodeling at the moment). So what are your thoughts? I like the idea, but perhaps there is a better brand that does the same thing.
