and last, some special ones

Joovy Caboose Ultralight, $229.99

This one is ideal when one of your children is older and has the stamina to walk most of the time but might get tired. They can either sit on the back bench or stand on the platform. It has a great basket and parent console for your crap. It might get a little cramped if the child in the front needs to recline, but otherwise seems like a great design, a great update of the Joovy Caboose.

I've seen this one around, and all I can say is wow, is it small! It has the profile of a Maclaren (in fact, weighing in at 27lb, it's exactly the same weight as the Maclaren Techno) but fits both children in. It seems possible that the one seated in the back might be a bit cramped, but it is supposed to be fine for two children, ages 3 months to 3 years each. Fantastic design, and it seems like it might be catching on, see the Eddie Bauer Tandem Montecito (no word on how much it weighs, but it looks a little larger).
