I would keep the one I have (a something-or-other-bottom-to-middle-of-the-line-that-Rich's-father-picked-out-when-he-was-in-charge-of-Rich's-grandfather's-finances model) until I need to replace it. Or, until my pookie-schnookums convinces me to put in the turquoise Westinghouse FL from the '50's... if it fits.
