Both my twins hated the FP Takealong swings. We received the Ocean wonders Takealong as a gift and a friend lent me her older FP Takealong swing. They hated them both.
I've had EXCELLENT experience with the basic Graco open-top swings (they don't plug in but I rarely had to change batteries).
I've also had excellent (no, make that AWESOME) experience with the Graco Sweetpeace. I really think the Sweetpeace provides more for the money (comes with swaddling wrap, the base can stand alone as a bouncy seat, Graco infant carseats can be used in the swing instead of the base, can plug in, has excellent, speaker-like sound quality, etc.). Weight limit is 25lbs.
