so now that induction burners are down to the point where i could afford one, i'd love to get one for my house. trouble is, there's tons of them on the market, and i don't know enough about them to know which is best--does it even matter? is there really anything like a "best" induction burner? and for clarification, i guess by "best," i really mean one that has the widest temperature range, as well as general quality of construction. thanks!
