That Sanyo model looks like a real heavyweight, full-featured mini. Hope the twins sound as good as they look... or at least better than your average, garden-variety, flimsy mini.
Oh... and I really like how you seem to be collecting families of boxes. Trust me... it's a very enjoyable/worthwhile pursuit! Whenever I buy a new (to me) type of boomer, I automatically make a commitment to find every version of that box I possibly can.
