This is the one I have:
It's from Black and Decker, cordless, stainless steel, and at least where I bought mine I could pick from different colors (so mine is red instead of steel colored, it makes me happy). I have had it for about a year with no issues - and no other kettle I've had has lasted past the 3 month mark. Of course, this is the first stainless steel kettle I've bought, the others have been plastic and ended up cracking.
30 minutes is too long to wait for coffee.
I'd start searching for large rocks to hit things with around the 10 minute mark
